N39.00001: Quantum and nonlinear photonics in silicon carbide Invited Speaker: Melissa A Guidry Silicon carbide as a host material uniquely combines CMOS compatible photonics with high-quality optically interfaced spin qubits and strong optical nonlinearities. In this talk, I will describe two directions which leverage these properties: (i) multi-emitter cavity quantum electrodynamics; and (ii) study of the quantum physics of soliton microcombs. |

N39.00002: Scalable integration of silicon nanophotonic devices on silicon carbide substrates Clayton T DeVault, Abram L Falk, F. Joseph Heremans, Alan M Dibos, David D Awschalom, Alexander A High Silicon carbide has emerged as a promising material for on-chip quantum and nonlinear nanophotonic devices. In addition to its excellent optical, electrical, and material properties, silicon carbide hosts optically active color centers and has a large intrinsic second-order nonlinear susceptibility. Here, we present a scalable, on-chip approach toward CMOS-compatible silicon-on-silicon carbide hybrid platforms via direct wafer bonding. Our optimized bonding method yields large-area, defect-free, uniform films with minimal oxide at the silicon-silicon carbide interface. By etching crystalline silicon nanophotonic waveguides and ring resonators into the silicon layer of the heterogenous film with well-established silicon fabrication methods that do not deteriorate the silicon carbide, we are able to fabricate high-quality, near-infrared resonators. This wafer scalable hybrid photonics platform could be an important step towards silicon carbide quantum technologies. |

N39.00003: Low- to Room-Temperature Studies of Silicon Nitride Single Photon Emitters Zachariah O Martin, Alexander Senichev, Samuel Peana, Benjamin J Lawrie, Alexei S Lagutchev, Alexandra Boltasseva, Vladimir M Shalaev We recently developed a method for generating intrinsic single-photon emitters in silicon nitride (SiN) by thermal annealing of low autofluorescence SiN films. We found that the intrinsic emitters in SiN are bright, stable, linearly polarized, and exhibit high single-photon purity at room temperature [1]. Also, we demonstrated the first realization of SiN waveguides with intrinsic quantum emitters and coupling of single-photon emission into the waveguide mode [2]. The exact atomic structure and energy levels of these emitters is yet to be fully understood. In this work, we study optical transition wavelengths, linewidths, and single-photon properties of these emitters as a function of temperature from 4K to 300K. We found the emergence of narrow emission lines at cryogenic temperatures, which have a linewidth of ~1 meV at 4.2 K. Furthermore, the intensity, linewidth, and wavelength of these peaks all show clear temperature dependence. The combination of temperature- and time-resolved measurements allows us to study the homogeneous and inhomogeneous broadening of emission. We will report on our study of the fundamental properties of single-photon emitters in SiN, which are critical for potential quantum photonic applications. |

N39.00004: Large-Scale Integration of Silicon Nitride Single Photon Emitters with Nanophotonic Elements Samuel Peana, Omer Yesilyurt, Zachariah O Martin, Alexander Senichev, Vahagn Mkhitaryan, Alexei S Lagutchev, Alexander Kildishev, Alexandra Boltasseva, Vladimir M Shalaev Recently bright and stable native single photon emitters (SPEs) were discovered in Silicon Nitride (SiN) [1]. These emitters have already been experimentally integrated with SiN waveguides, demonstrating their robustness to the stresses of fabrication and that successful monolithic integration with waveguides is possible [2]. However, the integration performed thus far has been done stochastically with respect to emitter position limiting overall performance and scalability. Recently, a high-yield (67%) and high spatial accuracy (~±30nm) lithographic process for creating these emitters was discovered. This process consists of rapid thermal annealing SiN/SiO2 nanopillars. In this presentation, we report on our progress in merging this novel large-scale site-controlled process with conventional photonic fabrication processes. The goal of these efforts is to develop a multistage fabrication process is capable of producing photonic elements such as waveguide incouplers, free space out couplers, and other SiN photonic elements with precisely integrated SiN SPEs. |

N39.00005: Contactless Excitation of Acoustic Resonance in Insulating Wafers Gan Zhai Contactless excitation and detection of high harmonic acoustic overtones in a thin insulator single crystal are described using radio frequency spectroscopy techniques. Single crystal [001] silicon wafer samples were investigated, one side covered with a Nb thin film, the common starting point for fabrication of quantum devices. The coupling between electromagnetic signals and mechanical oscillation is achieved from the Lorentz force generated by an external magnetic field. This method is suitable for any sample with a metallic surface or covered with a thin metal film. High resolution measurements of the temperature dependence of the sound velocity and elastic constants of silicon are reported and compared with known results. |

N39.00006: Multi-scale modeling of entangled photon generation with metal-organic framework materials Felipe F Herrera, Rubén A Fritz, Simon Paiva The design of new materials for entangled photon pair generation with high efficiency can accelerate the development of quantum optical technologies such as quantum communication and photonic quantum computing. Metal-organic frameworks (MOF) have emerged as suitable candidates for building tailor-designed optical crystals that can be used for the generation of entangled photon pairs via spontaneous parametric down-conversion (SPDC) with tunable phase matching [1]. We develop a multi-scale computational workflow for estimating the generation efficiency and coherence properties of entangled photon pairs produced via type-I and type-II SPDC in nonlinear MOF crystals, and compare with other noncentrosymmetric optical crystals using in the quantum industry [2]. For a MOF waveguide geometry pumped by focused Gaussian pump beams, we compute two-photon correlation correlation spectrum and entangled pair production rates for a set of experimentally-relevent zinc-tetrazole MOFs. We predict entangled photon properties and brigthness that are comparable or better than beta-barium borate (BBO). Our work provides the methodological grounds for developing large-scale screening tools for the discovery of MOF materials for optical quantum technology. |

N39.00007: Multichannel distribution and transformation of polarization-entangled photons with dielectric metasurfaces Ruwen Peng, Ya-Jun Gao, Zheng Wang, Yue Jiang, Mu Wang Photonic quantum information processing relies on operating the quantum state of photons, which usually involves bulky optical components unfavorable for system miniaturization and integration. In this work [1], we report on the transformation and distribution of polarization-entangled photon pairs with multichannel dielectric metasurfaces. The entangled photon pairs interact with metasurface building blocks, where the geometrical-scaling-induced phase gradients are imposed, and are transformed into two-photon entangled states with the desired polarization. Two metasurfaces, each simultaneously distributing polarization-entangled photons to spatially separated multiple channels M (N), may accomplish M × N channels of entanglement distribution and transformation. Experimentally we demonstrate 2 × 2 and 4 × 4 distributed entanglement states, including Bell states and superposition of Bell states, with high fidelity and strong polarization correlation. We expect this approach paves the way for future integration of quantum information networks. |

N39.00009: Polarization-based quantum logic gates using anisotropic excitonic media Devarshi Chakrabarty, Avijit Dhara, Pritam Das, Shreya Paul, Sajal Dhara The low symmetry of Group VII transition metal dichalcogenides (TMDs) confers to them intricate anisotropic optical and electronic properties. Rhenium disulfide (ReS2), a material belonging to this family, exhibits two kinds of bright in-plane excitons with linearly polarized transition dipole moments nearly orthogonal to each other, as evidenced from their polarized photoluminescence emission [1]. In this work, we discuss the potential of using such a pair of anisotropic exciton species and the inherent polarization mixing found in biaxial crystals to realize quantum logic gates for photon polarization-based qubits. Such a system offers a new path to easily integrable quantum processing devices. |

N39.00010: Programmable Quantum Simulation in Carbon Nanotube Exciton-Polariton at Room Temperature HeeBong Yang, Ahmet Gulsaran, Na Young Kim Quantum simulation is an analog quantum computation, one of the quantum computing streams, which mimics a real system in a small device to solve physics problems, in the context of the Hamiltonian engineering. There are several quantum simulation platforms, trapped-ion simulators, ultracold atom simulators, and superconducting simulators. Exciton-polariton is relatively easy to access to the measurements and obtain the results. Amongst polariton cases, strongly coupled interaction between a photon and matter, microcavity exciton-polariton is normally employed, which comes from a miniaturized Fabry-Pérot cavity to capture photons to couple with gain media. Conventional gain media, III-V materials, have been investigated with outstanding results, but cryogenic temperature is required due to the small binding energy and high-cost fabrication technique. For the room temperature operation, gain media of large-bandgap semiconductors, organic materials, transition metal dichalcogenides (TMDCs), and perovskites are studied. Here we introduce single-walled carbon nanotubes (SWCNTs) as SWCNTs are known to have high binding energy with selective energy bandgaps depending on the chirality. Furthermore, we would like to introduce programmable lattices with laser profile engineering with a spatial light modulator in order to tackle a variety of physics problems. |

N39.00011: Nanoscale THz Spectroscopy of Electrically Gated Graphene Nanoribbons Melanie Dieterlen, Erin Sheridan, Pubudu G Wijesinghe, Ki-Tae Eom, Chang-Beom Eom, Jeremy Levy Graphene nanoribbons (GNRs) have shown many interesting electrical and optical properties. We have developed a novel optical spectrometer capable of probing the nonlinear optical response of nanoparticles with dimensions ~10 nm or less, over a wide range of frequencies in THz and near-infrared [1]. The experiments take advantage of strong nonlinearities in SrTiO3 and the ability to “write” conductive nanowires at the LaAlO3/SrTiO3 (LAO/STO) interface, with ~10 nm gaps that are co-located with a GNR. We will probe GNRs individually under the influence of large electric fields (~1 MV/cm) with various geometries of electric gates that are both static and dynamic. |

N39.00012: Quantum paraelectric electro-optics Christopher P Anderson, Daniil M Lukin, Erik Szakiel, Joshua Yang, Alex D White, Giovanni Scuri, Melissa A Guidry, Kasper Van Gasse, Wentao Jiang, Amir H Safavi-Naeini, Jelena Vuckovic Efficient modulation is the key capability that enables advances in classical and quantum photonics. For this purpose, electro-optic materials have permeated applications ranging from quantum transducers and frequency combs to interconnects in data centers. In this talk, I motivate that materials near phase transitions are exciting platforms that display a high dielectric constant linked to an enhanced electro-optic tunability. Specifically, the perovskite SrTiO3 (STO) displays a quantum paraelectric phase at low temperature, where the cryogenic dielectric constant becomes massive but remains stable to near zero temperature. As a result, we predict that STO should display an electro-optic coefficient orders of magnitude higher than leading systems. First, I will discuss our efforts in experimentally measuring the cryogenic electro-optic coefficient in this material. I will then describe the creation of thin films of STO for integrated quantum photonics, and patterning into monolithic and hybrid resonators. Finally, I'll overview the opportunities for this previously unexplored material for use in photonic quantum computing, microwave-to-optical transduction, and for scaling superconducting processors. |
