Full-Field, Carrier-Less, Polarization-Diversity, Direct Detection Receiver based on Phase Retrieval [PDF]
, 2019 We realize dual-polarization full-field recovery using intensity only measurements and phase retrieval techniques based on dispersive elements. 30-Gbaud QPSK waveforms are transmitted over 520-km standard single-mode fiber and equalized from the receiver

A Transponder Aggregator with Efficient Use of Filtering Function for Transponder Noise Suppression [PDF]
, 2022 Colorless, directionless, and contentionless reconfigurable optical add/drop multiplexing (CDC-ROADM) provides highly flexible physical layer network configuration. Such CDC-ROADM must operate in multiple wavelength bands which are being increasingly implemented in optical transmission systems. The operation in C+L bands requires switch devices used in

Performance Analysis of Microwave Photonic Spectral Filters based on Optical Microcombs
Advanced Physics Research, Volume 4, Issue 1, January 2025.A comprehensive analysis of microcomb‐based microwave spectral filters based on the transversal filter approach is presented. Theoretical limitations in the filter spectral response from finite tap numbers, experimental errors, and the influence of the input signal's bandwidth are all analyzed.
