We fabricated GaN metasurfaces doped with InGaN quantum dots by templated molecular beam epitaxy (MBE) that support tunable high Q-factor quasi-bound states in the continuum (q-BICs) and demonstrated efficient optical nonlinear conversion using this platform.

We experimentally demonstrated a nonlocal, wavefront-shaping metasurface that focuses narrowband of green light but behaves like transparent substrate over broad visible spectrum.

We experimentally demonstrate Si-rich SiN nonlocal metalenses that operate across the entire visible spectrum. These devices shape wavefront at spectrally narrowband resonances but otherwise act like unpatterned substrates.
