V55.00001: Non-linear Optical Properties of Nanostructured Metamaterials. Ulises Meza, Bernardo Mendoza Santoyo, W Luis Mochan We present a theoretical study of second harmonic generation (SHG) in structured metamaterials; particularly, an array of cross-shaped vacuum inclusions within a silver host. We calculate the nonlinear susceptibility tensor, for a large number of geometrical configurations for the inclusions. We demonstrate that both, the SHG intensity and the resonance peaks are highly sensitive to even subtle changes in the geometry that break the centrosymmetry of the array of inclusions. The intensity in nonlinear susceptibility tensor depends on the variation in the symmetry of the metamaterial. We present the three non-zero components of that tensor, calculated by Haydock Recursive Method. We presented the results for calculation of non linear susceptibility of second order for a metamaterial composed by silver host and cross-shaped inclusions of vacuum. In addition, we are capable to extract from our calculations the nonlinear polarization, the induced electric field and the charge distribution in order to provide more information about the behavior of this type of metamaterials. |

V55.00002: Polariton lasing in nonresonantly driven coupled planar microcavities Krzysztof Sawicki, Thomas Jebb Sturges, Maciej Sciesiek, Tomasz Kazimierczuk, Kamil Sobczak, Wojciech Pacuski, Michal Nawrocki, Jan Suffczynski Multi-level exciton-polariton systems offer an attractive platform for studies of nonlinear phenomena resulting from the strong light-matter interaction. We demonstrate Bose-Einstein condensation of polaritons and dual-wavelength polariton lasing in a non-resonantly driven, vertically coupled microcavities. Time-resolved measurements reveal the complex dynamics of the processes responsible for the excitation transfer between the exciton reservoir and polariton levels. In particular, we observe that condensates at polariton branches do not form simultaneously following the excitation pulse. Moreover, we find that the presence of the condensate triggers energy-degenerate parametric oscillation, so far observed only under resonant excitation. Non-resonant excitation enables a clean observation of the scattering effects thanks to a spectral separation of the excitation and measured signal. Our findings, described by open-dissipative Gross-Pitaevskii equation coupled to reservoir rate equations, offer an insight into the factors governing dynamics of polaritons in a multi-level system. The inherent tunability of our platform is promising for the realization of photonic devices, such as polariton-based logic gates and constructing polariton lattices enabling two-dimensional hopping. |

V55.00003: Light-Cone Surface Lattice Resonances Enable Rotationally Tunable Edge Lasing Jun Guan, Marc Bourgeois, Ran Li, Jingtian Hu, Richard D Schaller, George C Schatz, Teri W. Odom This talk describes how the discovery of light-cone surface lattice resonances (SLRs) enables tunable edge-emitting lasing. We theoretically predict that optical modes on the light cone of an appropriately designed plasmonic nanoparticle lattice show in-plane scattering. The scattering direction was probed by using dye molecules as local gain media for edge-emitting lasing from the lattice. By investigating the light-cone SLR modes outside the first Brillouin zone, we observed multiple SLR modes along different lattice directions. Incorporating dye molecules with broadband photoluminescence into the lattices resulted in multi-color lasing emission with different in-plane directions. Our discoveries provide a laser design strategy to realize tunable lasing wavelength by rotating plasmonic nanoparticle lattices. |

V55.00004: DC Flux Dependance of Intermodulation Products in Nonlinear RF-SQUID Metamaterials Ethan Zack, Johanne Chitzanidis, Nikos Lazarides Radio Frequency (RF) Superconducting Quantum Interference Device (SQUID) metamaterials have demonstrated strong intrinsic nonlinearity [PRB 94, 174507 (2016)] as well as complex collective behavior [PRE 95, 050201 (2017); APL 114, 082601 (2019)]. In the case of multi-frequency excitation, intermodulation (IM) products can be strongly enhanced, or suppressed, by tuning frequency and RF flux amplitude. However, the DC flux dependence of these IM products has yet to be explored. This presentation will compare experimental data of the DC flux dependence to several numerical and analytic models of the rf-SQUID. Further, these models explain multi-stable transitions near the geometric resonance and predict the existence of chaotic behavior in a single rf-SQUID [Chaos 28, 063117 (2018)]. These features should be visible to future experiments and could potentially lead to the discovery of new and useful behaviors in rf-SQUID metamaterials. |

V55.00005: Realizing Anderson localization of surface plasmon polaritons and enhancing their interactions with excitons in disordered nanostructures Ruwen Peng, Bo Xiong, Ren-Hao Fan, Mu Wang Surface plasmon polaritons (SPPs) propagating on metal-dielectric interface suffer from evitable energy losses originated from metals, especially at visible regime, which degrades the quality of SPP-based devices. However, if the size of the devices is sufficiently miniaturized, we can thereby circumvent the problems of large propagation losses. Anderson localization is a possible approach to squeeze SPPs. In this work, we experimentally demonstrate the Anderson localization of SPPs at optical frequencies in both 1D and 2D nanostructures. By increasing the positional disorder of the silver nanoslit arrays and the silver nanohole arrays, strong localization of SPPs appears with an exponentially decreased electric field, the reduced propagation length and the rapid disappearance of the autocorrelation coefficient. Moreover, we manage to enhance the localized SPP-exciton interactions in the 2D disordered silver nanoarrays combined with fluorescent dye molecules. Our study extends Anderson localization of SPPs at visible regime to low-dimensional disordered systems, and provides a unique way to enhance light-matter interaction in SPP-based nanodevices. |

V55.00006: Exciton-plasmon coupling in ultrathin periodically aligned carbon nanotube arrays. Chandra M Adhikari, Igor Bondarev We study theoretically the in-plane electromagnetic response and the exciton-plasmon interactions for an experimentally feasible carbon nanotube (CN) film systems composed of parallel aligned periodic semiconducting CN arrays embedded in an ultrathin finite-thickness dielectric[1,2]. For homogeneous single-chirality CN films, the intertube coupling and the thermal broadening bring the exciton and interband plasmon resonances closer together. These resonances can overlap due to the inhomogeneous broadening for films composed of array mixtures with a slight CN diameter/chirality distribution. In such systems the real part of the response function is negative for a broad range of energies (negative refraction band), and the CN film behaves as a hyperbolic metamaterial. We also show that for a properly fabricated two-component utrathin CN film, by varying the relative weights of the two constituent CN array components one can tune the optical absorption profile to make the film transmit or absorb light in the neighborhood of an exciton absorption resonance on-demand. – [1]C.M.Adhikari and I.V.Bondarev, MRS Advances, doi10.1557/adv.2020.234; [2]C.M.Adhikari and I.V.Bondarev, arXiv2010.00139. |

V55.00007: Controlling photonic quantum states by a metasurface Quanwei Li, Wei Bao, Zhaoyu Nie, Yang Xia, Yahui Xue, Yuan Wang, Sui Yang, Xiang Zhang The two-dimensional designer metasurfaces have been established as a new class of versatile and powerful optical solution for controlling the classical light in various degrees of freedom such as phase, amplitudes, polarization and angular momentum. Expanding the control capability of metasurface from classical light to quantum state of single photons is an emerging direction that can lead to a new regime of light-matter interaction and applications for quantum technology. In this talk, we will present our proposal and experimental demonstration of manipulating photonic quantum states enabled by an unprecedented design of metasurface. We show the control over the quantum states and the effective quantum interaction between single photons, which is impossible by traditional optics. Our work greatly empowers the operations and functionalities of optical quantum technologies. |

V55.00010: Spontaneous emission dynamics of Eu3+ ions coupled to hyperbolic metamaterials Gabriel López-Morales, Mingxing Li, Ravindra Kumar Yadav, Harshavardhan R. Kalluru, Jaydeep Basu, Carlos Meriles, Vinod Menon We investigate a system comprising of Eu3+(NO3)3 nanocrystals on a hyperbolic metamaterial (HMM) structure featuring a hexagonal array of Ag-nanowires in a porous Al2O3 matrix. HMM-coupled Eu3+ ions exhibit up to 2.4-fold increase of their decay rate, accompanied by an enhancement of its 5D0→7F2 transition emission rate. Using FD-TD modeling, we corroborate these observations with the increase in the photonic density of states seen by the Eu3+ ions in the proximity of the HMM. Our results indicate HMMs can serve as a valuable tool to control the emission from weak transitions, and hence hint at a route towards more practical applications of rare-earth ions in nanoscale sensing and optoelectronic devices. |
