Performance Of Microwave Photonic Filter Research Articles

Investigation on microwave photonic filter group delay performance

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.

An Investigation of the Operation and Performance of Coherent Microwave Photonic Filters

We present a theoretical analysis of coherent microwave photonic filters (MPFs), which employ intensity modulation and direct detection. Expressions for the frequency dependent power gain are derived. The noise and distortion performance of MPFs is also analyzed. Two example filter implementations are given which provide a 100-MHz passband centered at 40 GHz.
