A novel dual-single-sideband Kramers-Kronig reception without performance penalty enabled by time-slot coding is proposed for multi-user indoor optical wireless communications with few-mode based beam shaping to improve system spectral efficiency.

We proposed a remote power-over-fiber system by introducing delta-sigma modulation to simultaneously simplify deployment of remote radio heads and reduce cost. It extends the remote distance to 4-km and realizes 37.2% optical power transmission efficiency.

We propose a ditherless bias control algorithm, which uses relative detection and neural network to predict bias state. Experimental results show the precision is 1.5% and 0.3% of 2V π for bias IQ and P.
