Bound states in the continuum are optical modes with extremely high-quality factors and
narrow resonances, which exist in the dispersion spectrum of the radiative region above the …

We demonstrate all-optical modulation with a near-unity contrast of nonlinear light
generation in a dielectric metasurface. We study third-harmonic generation from silicon Fano …

Optical limiters reduce transmittance under increasing incident optical power and protect
sensitive components against high-intensity illumination. Vanadium dioxide (VO 2), which is …

High-Q optical resonances in nonlocal metasurfaces, benefiting from significantly enhanced
light/matter interactions, feature strong responses even under a weak external stimulus. In …

We present the design of an asymmetric metasurface made of germanium antimony
tellurium nanowires that supports quasibound states in the continuum. A fully coupled …

Huygens metasurfaces have demonstrated remarkable potential in perfect transmission and
precise wavefront modulation through the synergistic integration of electric resonance and …

The development of sensitive analytical methods is of prime importance for the detection of
pesticide residues on the surfaces of fruits and vegetables at extremely low concentrations …

Time-resolved optical spectroscopies are emerging as a go-to technique for non-destructive
testing of nanomaterials. Inspecting the thermal and mechanical properties of a mesoscale …

Liquid crystal on silicon (LCoS) panels, renowned for their high resolution and fill-factor, are
integral to modern projection displays. However, their inherent polarization sensitivity …

Ultrafast excitation of non-equilibrium carriers under intense pulses offer unique
opportunities for controlling optical properties of semiconductor materials. In this work, we …
