An Optimal Design of 25-GHz Flat-top Multichannel Optical Filters

Abstract

We propose a new design of 25-GHz flat-top multichannel optical filter. The flat-top of optical filters can improve to 2.288×10-11dB which is superior to that of 5 orders of previous study. The superior performance of dispersion and channel spacing isolation improve 73.5% and 94%, respectively, which compared with current available commercial products and previous study.
