TL;DR: In this article, a silicon-on-insulator photonic integrated circuit is used as a building block in photonic-based beamforming networks for 5G wireless systems, which consists of an optical de-interleaver for carrier-sideband separation, a microring resonator-based phase-shifter (PS) and a carrier depletion-based MRR electro-optic modulator.

TL;DR: In this paper, an all-optical NRZ-DPSK to RZ-OOK converter employing an optical delay line interferometer and a semiconductor optical amplifier is described.

TL;DR: Experimental results show increased tolerance to the optical signal-to-noise ratio (OSNR) obtained from clustering methods based on k-mean and fuzzy c-means Gustafson-Kessel algorithms, and improvements to the bit error rate are obtained without requiring additional compensation algorithms.

TL;DR: The field trial results of the first photonics-based radar system in a real maritime environment are presented, detecting naval targets on both long range and harbor maneuvering and highlighting the excellent performance and promising improvements.
