Synthesizing planar holographic Bragg reflectors with layer-peeling algorithm

We have developed the design method for planar holographic Bragg reflectors by layer-peeling algorithm. We have modified the layer-peeling algorithm to synthesize planar holographic Bragg reflectors. We use iterative layer-peeling algorithm with fabrication constraints to solve the difficulties of fabricating the negative parts of apodization and shorten the length in planar holographic Bragg reflectors. The novel designs for the passband WDM filter that we have demonstrated is easier to manufacture.
