摘要

Investigation on the group delay performance of microwave photonic filters is presented.Analysis and simulation results show symmetrical distribution on the delayed optical signals in the impulse response is required to obtain a constant group delay performance.Experimental results for both symmetrical and asymmetrical tap distribution microwave photonic notch filters are presented showing the group delay response with ＜±25 ps and around 1 ns ripples,respectively.
