Nonlinear van der Waals metasurfaces with resonantly enhanced light generation
Haonan Ling, Yuankai Tang, Xinyu Tian +5
Efficient nonlinear wave mixing is of paramount importance for a wide range of applications. However, weak optical nonlinearities pose significant challenges for accessing nonlinea…
Charge and Energy Transfer Dynamics of Hybridized Exciton-Polaritons in 2D Halide Perovskites
Surendra B. Anantharaman, Jason Lynch, Christopher E. Stevens +14
Excitons, bound electron-hole pairs, in Two-Dimensional Hybrid Organic Inorganic Perovskites (2D HOIPs) are capable of forming hybrid light-matter states known as exciton-polariton…
Coherent radiation from a chain of charged particles on a circular orbit around a dielectric ball
L. Sh. Grigoryan, A. H. Mkrtchyan, S. B. Dabagov +5
We investigate the electromagnetic radiation from a chain of relativistic charged particles uniformly rotating along equatorial orbit around a dielectric ball. For weak absorption…
Invertible Optical Nonlinearity in Epsilon-near-zero Materials
Chentao Li, Xinyu Tian, Guoce Yang +4
Epsilon-near-zero (ENZ) materials such as indium tin oxide (ITO), have recently emerged as a new platform to enhance optical nonlinearities. Here we report a theoretical and experi…
Second Harmonic Generation from a Single Plasmonic Nanorod Strongly Coupled to a WSe2 Monolayer
Chentao Li, Xin Lu, Ajit Srivastava +5
Monolayer transition metal dichalcogenides, coupled to metal plasmonic nanocavities, have recently emerged as new platforms for strong light-matter interactions. These systems are…
Brillouin Light Scattering of Spin Waves Inaccessible with Free-Space Light
R. Freeman, R. Lemasters, T. Kalejaiye +8
Micro-focus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentu…
Time-variant metasurfaces enable tunable spectral bands of negative extinction
Maxim R. Shcherbakov, Robert Lemasters, Zhiyuan Fan +4
We demonstrate that rapidly switched high-Q metasurfaces enable spectral regions of negative optical extinction.
Enhancing second harmonic generation using dipolar-parity modes in non-planar plasmonic nanocavities
Feng Wang, Manoj Manjare, Robert Lemasters +2
There is an active demand to develop efficient nanoscale nonlinear sources for applications in photonic circuitry, quantum optics and biosensing. To this end, plasmonic systems hav…
Controllable Optical Negative Refraction and Phase Conjugation in Graphene
Hayk Harutyunyan, Ryan Beams, Lukas Novotny
The development of optical metamaterials has resulted in the demonstration of remarkable physical properties, including cloaking, optical magnetism, and negative refraction. The la…
