We demonstrate for the first time, a uniform low temperature (<250 °C) process for fabricating both high-confinement thick and low-confinement thin ultra-low loss Silicon nitride waveguides.

High efficiency and dynamic modulation of third-harmonics generation (THG) is realized by integrating the giant nonlinear responses resulted from intersubband transitions of multiple quantum well (MQW) with plasmonic nano-resonator.

Recent advances in understanding the intricate hot-electron dynamics in plasmonic nanostructures enable efficient hot-carrier generation, transport, and manipulation, driving technological innovations in photodetection, solar cells, photocatalysis, and ultrafast nanophotonics.

We experimentally demonstrate high-quality infrared imaging ranging from >1000 to 4000 nanometers with Si metasurfaces based on four-wave mixing (FWM) processes, by employing a pump beam at resonant position.

A liquid crystal spectral singlet lens unifying optical imaging and computational spectrometry functions enables the creation of minimalist, miniaturized and high-performance hyperspectral cameras.

We propose a plasmonic effect-assisted pyroelectric detector covered by an inhomogeneous Al metasurface, which exhibits ultrafast response speed and extended near-infrared response spectrum.

Strain control of quasi-1D ZrSe₃ enables ultrafast, polarization-selective optical switching with enhanced selectivity and tunable switching energies.
