High resolution multispectral spatial light modulators based on tunable Fabry-Perot nanocavities
Shampy Mansha, Parikshit Moitra, Xuewu Xu +6
Spatial light modulators (SLMs) are the most relevant technology for dynamic wavefront manipulation. They find diverse applications ranging from novel displays to optical and quant…
Continuous wave second harmonic generation enabled by quasi-bound-states in the continuum on gallium phosphide metasurfaces
Aravind P. Anthur, Haizhong Zhang, Ramon Paniagua-Dominguez +5
Resonant metasurfaces are an attractive platform for enhancing the non-linear optical processes, such as second harmonic generation (SHG), since they can generate very large local…
Nonlinear interferometry with infrared metasurfaces
Anna V. Paterova, Dmitry A. Kalashnikov, Egor Khaidarov +5
The optical elements comprised of sub-diffractive light scatterers, or metasurfaces, hold a promise to reduce the footprint and unfold new functionalities of optical devices. A par…
Lasing action in single subwavelength particles supporting supercavity modes
Vasilii Mylnikov, Son Tung Ha, Zhenying Pan +4
On-chip light sources are critical for the realization of fully integrated photonic circuitry. So far, semiconductor miniaturized lasers have been mainly limited to sizes on the or…
Demonstration of second harmonic generationin gallium phosphide nano-waveguides
Aravind P. Anthur, Haizhong Zhang, Yuriy Akimov +4
We designed, fabricated and tested gallium phosphide (GaP) nano-waveguides for second harmonic generation (SHG). We demonstrate SHG in the visible range around 655 nm using low pow…
Control of LED Emission with Functional Dielectric Metasurfaces
Egor Khaidarov, Zhengtong Liu, Ramon Paniagua-Dominguez +8
The improvement of light-emitting diodes (LEDs) is one of the major goals of optoelectronics and photonics research. While emission rate enhancement is certainly one of the targets…
