Abstract: We experimentally demonstrate an orthogonal frequency-division multiplexing (OFDM) system with direct detection. Adopting Kramers–Kronig (KK) detection and probabilistic shaping (PS) technology, 140-Gb/s 256-QAM signal can be successfully transmitted over 25-km standard single-mode fiber (SSMF), which… read more here.

Abstract: An efficient nonlinear equalizer based on the pruning I/Q-joint deep neural network (DNN) is proposed and experimentally demonstrated to mitigate the nonlinearity in a photonics-assisted millimeter-wave (MMW) system with a high-order 256 quadrature-amplitude-modulation (QAM) format.… read more here.
