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.

Sub-Nyquist Field Trial Using Time Frequency Packed DP-QPSK Super-Channel Within Fixed ITU-T Grid
, 2015 Sub-Nyquist time frequency packing technique was demonstrated for the first time in a super channel field trial transmission over long-haul distances. The technique allows a limited spectral occupancy even with low order modulation formats.

HeCSON: Heuristic for Configuration Selectionin Optical Network Planning
, 2020 We present a transceiver configuration selection heuristic combining Enhanced Gaussian Noise (EGN) models, which shows a 40\% increase in throughput and 87\% decrease in execution time, compared to only approximate EGN and Full-Form EGN ...

IEEE Photonics Journal, 2014 We propose a novel method of in-band estimation of optical signal-to-noise ratio (OSNR) using a digital coherent receiver, where OSNR is determined from second- and fourth-order statistical moments of equalized signals in any modulation format.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement
IET Communications, Volume 19, Issue 1, January/December 2025.Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Optical signal to noise ratio monitoring using single channel sampling technique.
Optics Express, 2014 In this paper, we propose a novel method to depict 2-dimension (2-D) phase portrait by using single-channel-sampling (SCS) technique, which can be used for optical performance monitoring.
