Stimulated Brillouin Scattering by Dual Lasers Pumping in WGM Microcavities
Published 2020-01-01Get full textStimulated Brillouin scattering (SBS) is experimental investigated in several hundred microns in diameter microspheres with a little eccentricity by melting a fiber tip in a fusing splicer. Fourth order cascaded SBS at C-band (∼1540 nm) with 27 mW can be achieved with the abund...

Tunable Electro- and All-Optical Switch Based on Epsilon-Near-Zero Metasurface
Published 2020-01-01Get full textA novel design of a tunable optical switch based on epsilon-near-zero (ENZ) metasurface is proposed, which can work as an electro-optical or an all-optical switch, and be tuned by gate-voltages, incident angles, and intensity of pump light. The result shows that the coupling of the ENZ mode and plas...

Optimization of Surface Configuration in IRS-Aided MIMO-VLC: A BER Minimization Approach
Published 2024-01-01Get full textDue to its ability to reconfigure the optical channel, intelligent reflecting surface (IRS) has revealed its great potential for enhancing the performance of visible light communication (VLC) systems. In this paper, we apply a mirror array-based IRS in typical multiple-input multiple-output based VL...

Observation of Soliton Molecules in a Robust All PM Mode-Locked Fiber Laser With Nonreciprocal Phase Bias
Published 2021-01-01Get full textWe report the first experimental observation, to the best of our knowledge, of soliton molecules in a robust all polarization-maintaining (PM) mode-locked fiber laser with a nonreciprocal phase bias that results in a low self-starting threshold and stable mode locking. Through elaborately tuning the...

Real-Time Multi-User Video Optical Wireless Transmission Based on a Parallel Micro-LEDs Bulb
Published 2021-01-01Get full textIn this work, we experimentally achieved a real-time video optical wireless transmission which can broadcast two users in different positions, simultaneously. Firstly, a single-pixel 50-μm micro-LED is designed and fabricated on a GaN-based wafer and then two micro-LED chips are connected...
