Chemical Vapor Deposition of Spherical Amorphous Selenium Mie Resonators for Infrared Meta-Optics

Danveer Singh et al.

Summary: A chemical vapor deposition technique has been utilized to deposit amorphous selenium spheres on various substrates and characterize their Mie-resonant response in the mid-infrared spectral range. The amorphous selenium spheres demonstrate size-tunable Mie resonances and strong absorption dips of up to 90% in a broad MIR range. Furthermore, ultra-high-Q resonances are observed when Se Mie-resonators are coupled to low-loss epsilon-near-zero substrates.

Dynamic Color Tuning with Electrochemically Actuated TiO2 Metasurfaces

Janna Eaves-Rathert et al.

Summary: The electro-chemical lithiation of anatase TiO2 to Li0.5TiO2 (LTO) enables dynamic visible color tuning with reduced absorption at high frequencies. The dynamic tunability of TiO2 can be leveraged in a Fabry-Perot cavity and a gap plasmon metasurface, showing competitive performance with established actuators like WO3.

Cascaded Optical Nonlinearities in Dielectric Metasurfaces

Sylvain D. Gennaro et al.

Summary: In this study, we demonstrate the existence of cascaded second-order optical nonlinearities by analyzing second- and third-wave mixing from a highly nonlinear metasurface. We find that the third-wave mixing signal from the cascaded process can be comparable in strength to that from conventional third-harmonic generation, and surface nonlinearities are the dominant mechanism contributing to cascaded second-order nonlinearities in our metasurface.

Enhanced Five-Photon Photoluminescence in Subwavelength AlGaAs Resonators

Anastasiia Zalogina et al.

Summary: Multiphoton processes of absorption photoluminescence have found diverse applications ranging from threedimensional microfabrication to biological imaging. However, studying higher-order photoluminescence processes at subwavelength scales has been challenging due to their low efficiency. In this study, we demonstrate the observation of five-photon luminescence from a single subwavelength nanoantenna at room temperature, enabled by the Mie resonances. The interaction of Mie multipolar modes at the subwavelength scale enhances the efficiency of five-photon luminescence by at least 4 orders of magnitude.

Complex optical conductivity of Bi2Se3 thin film: Approaching two-dimensional limit

Mingsheng Fang et al.

Summary: In this study, it was found experimentally that as the thickness of Bi2Se3 thin films approaches the two-dimensional limit, the zero-cross point of the imaginary complex optical conductivity exhibits a blueshift trend. This indicates that the optical properties of Bi2Se3 thin films are tunable as they approach the two-dimensional limit.
