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.
