摘      要：We present a method to optimize the flat-band long-period fiber Bragg grating (FBG) in this *** method is based on the p^rticle swarm optimization method and the matrix transmission *** optimized refractive modulation profile does not introduce so many phase shifts and is easier to fabricate compared with that of layer-peeling method which introduces lots of π phase shift at each zero point of apodization profile in designing for the same problem.

主 题 词：Optimization Phase shift
