S28.00002: Comparison of high-order harmonic generation in finite and bulk honeycomb lattices Christoph Juerss, Daniel Moos, Dieter Bauer The high-order harmonic generation in solid systems has been studied extensively in recent years. Most of the theoretical work focuses on the bulk of solids. Hence, edge effects, as in realistic systems, are neglected. In this work we provide a direct comparison of the harmonic spectra from finite systems and the bulk. The investigated systems are two-dimensional honeycomb lattices with either one (e.g., graphene) or two (e.g., hexagonal boron nitride) different atomic elements contained in the system. The calculation of the momentum-resolved spectra allows a deep insight of the electron dynamics inside the bandstructure and in position space. Electrons might be forced to move along the edges in the finite system if the incident laser is circularly polarized. In the bulk, such edge currents cannot occur. |

S28.00003: Engineering a Kerr-Based Deterministic Cubic Phase Gate via Gaussian Operations Tatsuhiro Onodera, Ryotatsu Yanagimoto, Edwin Ng, Logan Wright, Peter McMahon, Hideo Mabuchi We propose a deterministic, measurement-free implementation of a cubic phase gate for continuous-variable photonic quantum information processing. In our scheme, the applications of displacement and squeezing operations allow us to engineer the effective evolution of the quantum state propagating through an optical Kerr nonlinearity. Under appropriate conditions, we show that the input state evolves according to a cubic phase Hamiltonian and that the cubic phase gate error decreases inverse quartically with the amount of quadrature squeezing, even in the presence of linear loss. Finally, we study the experimental feasibility of the scheme and find that photonic platforms supporting strong spatial and temporal confinement of pulsed light in low loss and low dispersion nonlinear waveguides could enable an experimental demonstration in the near future. |

S28.00004: Effects of anharmonicity in a dual-Sagnac interferometer rotation sensor Stephen G Thomas, Andrew Smith, Charles Brantley Henry, Robert Sapp, Charles A Sackett, Charles W Clark, Mark Edwards A recent experiment implemented a dual Sagnac atom interferometer (AI) for rotation sensing using a Bose-Einstein condensate (BEC) confined in a TOP-trap potential. The BEC is split twice by laser light to create two pairs of counter-orbiting clouds in a lowest-order harmonic potential with each pair acting as a separate Sagnac interferometer. After one orbit the two overlapping cloud pairs are split again and the interference patterns are inferred from the population of atoms in the zero-momentum state. We have simulated the impact of the presence of anharmonic terms in the potential on the performance of the AI as measured in a recent experiment by using a variational approximation of the Gross-Pitaevskii equation (GPE) model. This model based on the Lagrangian Variational Method where the condensate pieces are represented by Gaussian clouds. We have compared the phase differences between the dual interferometers as computed in the model with that predicted by the action computed over the classical path for various types of anharmonic terms and for condensates of different sizes to assess the impact of these on interferometer performance. |

S28.00005: Observation of high-order Mollow triplet by quantum mode control with concatenated continuous driving GUOQING WANG, Yi-Xiang Liu, Paola Cappellaro The Mollow triplet is a fundamental signature of quantum optics and has been observed in numerous quantum systems. Although it arises in the ``strong driving'' regime of the quantized field, where the atoms undergo coherent oscillations, it can be typically analyzed within the rotating wave approximation. Here we report the first observation of high-order effects in the Mollow triplet structure due to strong driving. In experiments, we explore the regime beyond the rotating wave approximation using concatenated continuous driving that has less stringent requirements on the driving field power. We are then able to reveal additional transition frequencies, shifts in energy levels, and corrections to the transition amplitudes. In particular, we find that these amplitudes are more sensitive to high-order effects than the frequency shifts and that they still require an accurate determination in order to achieve high-fidelity quantum control. The experimental results are validated by the Floquet theory, which enables the precise numerical simulation of the evolution and further provides an analytical form for an effective Hamiltonian that approximately predicts the spin dynamics beyond the rotating wave approximation. |

S28.00006: Coherence and entanglement in mixed classical light Asma Al-Qasimi We study the analogue of quantum entanglement in mixed states of classical light, where we investigate the relationship between Polarization Coherence and the Entanglement between the degrees of freedom of light. For a specific class of states, we demonstrate how the coherence shared between these two properties shrinks in size as the level of purity decreases. |

S28.00007: Unidirectional flow of solitons with nonlinearity management Majed Alotaibi, S. M. Al-Marzoug, H. Bahlouli, Usama Al khawaja Unidirectional flow of solitons is obtained with a localized modulation of the nonlinearity strength. The modulation takes the shape of an asymmetric double well with a slight difference between the potential depths. The results were established using numerical computations and then verified qualitatively using a variational approach. Our results suggest that the most important physics at the origin of the unidirectional flow is the excitation of the breathing modes in the scattering region. Simplified variational equations of motion suggested that the phenomenon can be observed if the soliton is scattered by a generic asymmetric effective double potential well. |

S28.00008: Quantum Sensing with Fiber-Coupled Diamond Emitters Sean Blakley, Ilya Fedotov, Xinghua Liu, Christapher Vincent, Alexey Akimov, Philip Hemmer, Aleksei M Zheltikov Fluorescent defects in diamond are at the cutting edge of quantum sensor technology. When coupled to an optical fiber platform, in situ laser excitation and signal collection from these sensors is possible. The advent of microstructured fibers has enabled measurement modalities employing vector gradient field measurements, common-mode noise rejection, and scanning microresolution thermal and magnetic field imaging that can now be performed in environments without easy optical access. |

S28.00009: Using low-finess etalons and Bayer filters for low cost yet robust laser wavelength metrology Jason N Porter, Jarom S. Jackson, Dallin S. Durfee, Richard Sandberg Measuring the wavelength of a laser precisely is critical in multiple fields such as atomic spectroscopy, precision navigation, and even in gravitational wave detection. Here, we present a wavelength meter with picometer resolution based on etaloning effects of inexpensive glass slides and the built-in color filters of a low-cost CMOS camera. We demonstrate that after calibration with a standard commercial wavemeter, the device is accurate for over 16 days by regular testing with two tunable lasers. We determined the device's error is only 0.04 parts per million (ppm) within the first 24 hours and only increases to 0.90 ppm with a standard deviation of 5.29 ppm over a period of 16 days. |

S28.00010: Observation of photonic spin-momentum locking due
to coupling of achiral metamaterials and quantum dots Jaydeep Basu, Ravindra Kumar Yadav, Wenxiao Liu, Girish S Agarwal Chiral interfaces provide a new platform to execute quantum control of light-matter interactions. While there are reports of spin-momentum locking with combination of chiral emitters or chiral metamaterials it is not readily observable with both achiral emitters and metamaterials. We observe [1] clear signatures of directional and chiral emission from the hybrid system in wavevector resolved emission map in experiments. We report a new regime of spin-momentum locking phenomenon where extrinsic pseudo helicity of light is provided by coupling quantum emitters to evanescent high wavevector modes of hyperbolic metamaterials (HMM) using standard normal incidence illumination. Efficient coupling between quantum dots (QD) and the metamaterial leads to emergence of these photonic topological modes which can be detected in the far field. We provide theoretical explanation for the emergence of spin-momentum locking through rigorous modeling based on photon Green’s function where pseudo spin of light arises from coupling of QD to evanescent modes of HMM. |

S28.00011: Pulling a Structure With Laser Light by Regulation of Resonances Li-Fan Yang, Adam W. Behnke, Thomas J. Pollei, Kevin J. Webb The physical basis for pulling a passive nanostructured surface with light is presented and supported with numerical simulations of fields and force density in the material. A net optical force in the direction opposite to that of the incident light is described for a structure composed of a periodic array of slots in a gold film on a dielectric membrane and with single-plane-wave illumination. The force density due to a plasmon surface wave resonance on the back dominates and results in the structure being pulled towards the incident light. Previous pulling concepts relied on structuring an incident beam to influence motion of a small particle. In this case, by contrast, the structure is regulating the scattered field and hence influencing the net force. In addition, an example metal-dielectric structure is presented that allows pushing or pulling, depending on wavelength and whether the surface wave on the front or the back dominates, respectively. Such interplay between material, structure at the nanometer-scale, and optical force should have substantial consequences in applications that include all-optical communication, remote actuation, propulsion, and biophysics. |

S28.00012: Theory of four-wave mixing for biomolecular systems: Toward transduction of quantum information from fluorescent protein complexes to photonic readouts Matteo Gori, Gamze Gul, Prem Kumar, Philip Kurian The generation of photonic entanglement from fluorescent proteins (FPs) in aqueous solution has opened new opportunities for quantum-enhanced measurements in biomolecular environments. Theory suggests that quantum correlations in DNA and DNA-targeting enzymes can be probed on the spatial and temporal scales offered by these entangled photon experiments, which exploit nonlinear four-wave mixing (FWM) techniques. However, a clear theoretical framework describing the entangled outgoing signal and idler photons from the vibronic ground and excited state manifolds of the FPs is still lacking. We present a model for the FWM dynamics of two classical electromagnetic fields interacting with a matter density of FPs, each with two manifolds of states containing fine vibrational structure. Connecting the quantum state of the generated entangled photons to the internal molecular structure and dynamics of the statistical ensemble of FPs would lead to new experimental tests of our hypothesis that ultrashort pulses (~100 fs duration) can readout molecular correlations under ambient conditions. In the context of a warm and wet electrodynamic milieu, our results will be essential for designing bio-inspired quantum devices and robust quantum materials for room-temperature technology applications. |

S28.00013: Simulating the 3-State Potts Hamiltonian with a Coherent Network of Photonic Oscillators Mostafa Honari Latifpour, Mohammad-Ali Miri Recently, there has been much interest in physical simulation of spin models. This is largely driven by the fact that many important combinatorial optimization problems that are considered computationally hard problems can be formulated in terms of lattice spin models. These optimization problems can thus be efficiently solved by finding the ground state of the corresponding physical system. Here, we propose direct optical implementation of a three-state Potts spin model by using networks of coupled three-photon parametric down-conversion oscillators. The tristable phase of such a parametric oscillator acts like a three-state classical spin degree of freedom. We show that a dissipatively coupled network of such oscillators emulates the three-state classical Potts model and can be used as an all-optical solver for optimization problems such as MAX-3-CUT and graph 3-COL. The results can be further generalized to implement the n-state planar Potts model. |

S28.00014: Pushing Metacavities to the Quantum limit and beyond Johannes Dickmann, Steffen Sauer, Jan Meyer, Thomas Siefke, Ernst Rasel, Stefanie Kroker We present the progress in the field of optical cavities with metamirrors (metacavities). Metamirrors show theoretically on one hand the lowest thermal noise of all mirror technologies and on the other hand principally enable high reflectivity in combination with high spectral and angular tolerances. First experimental results on metamirrors in cavity experiments are presented. The reflectivity of the metamirrors are investigated using a two-stage experimental setup covering the reflectivity range of 0.2% up to almost 100%. We show spectroscopic measurement results for wavelengths ranging from 1450 to 1650 nm as well as reflectivity measurements using a cavity ringdown setup. The manifold capabilities of integrating multiple optical functions with one nanostructured layer pave the way to polarization-dependent mirrors, focusing elements, more effective squeezed-light cavities and ultra-stable metamirror cavities. |

S28.00015: Temporal imaging of the real-time dynamics in soliton crystals Futai Hu, Abhinav Kumar Vinod, wenting wang, Xinghe Jiang, Jaime Gonzalo Flor Flores, Mali Gong, Chee Wei Wong Dissipative Kerr solitons are pulses generated in Kerr nonlinear optical resonators, which achieve a combination between nonlinear optical physics and the integrated photonics. Recent work has found temporally-organized soliton ensembles, often called soliton crystal, could provide additional freedoms in engineering spectra and temporal behaviors compared to single solitons. Previous studies focus on the spectra and slow-time evolution, while less effort is contributed to dynamics in the round-trip scale. The underlying ultrafast dynamics are critical to understanding the formation, transformation, and quenching of these mode-locked states. |
