Abstract

Based on the theory of polarized light interference and multibeam interference, the transmission function of BGT Interleaver is provided in this paper. By theoretical analysis of the transmission function, it is found that higher reflectivity of G-T cavity means broader interleaver pass and isolation bandwidth and smaller contrast. Otherwise, the narrower the pass and isolation bandwidth and the largger contrast. The related experiments are designed and demonstrated to inspect BGT interleaver characteristics, from which restriction relationship is reached between bandwidth and contrast of BGT interleaver. The higher reflectivity of G-T cavity coresponses to better bandwidth and worse contrast. BGT Interleaver can be designed according to above.
