Ultra-low threshold continuous-wave quantum dot mini-BIC lasers
We demonstrate room-temperature, ultra-low threshold, continuous-wave, and single-mode operated quantum dot mini-BIC lasers in the O-band wavelength range, serving for a perspective light source for future photonic integrated circuits.

Near-field enhancement of optical second harmonic generation in hybrid gold–lithium niobate nanostructures
Upconversion of light from its fundamental wavelength (FW) to its second harmonic (SH) is enhanced 32× in micron-scale lithium niobate (LiNbO3) spheres through near-field interactions with gold (Au) nanoparticles.
