Dielectric microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

Microlasers have experienced tremendous development in the past decade and become an
essential part in laser evolution, as miniature lasers provide strong optical confinement and …

We propose how to achieve nonreciprocal quantum entanglement of light and motion and
reveal its counterintuitive robustness against random losses. We find that by splitting the …

A review for optical fiber hydrogen sensors based on palladium (Pd) and tungsten oxide
(WO 3) thin films is presented, with specific focus on the measurement methods, probe …

The realization of efficient on‐chip microlasers with scalable fabrication, ultralow threshold,
and stable single‐frequency operation is always desired for a wide range of miniaturized …

We propose nonreciprocal phonon lasing in a coupled cavity system composed of an
optomechanical resonator and a spinning resonator. We show that the optical Sagnac effect …
