Abstract

By means of the coupling mode theory and the method of the extension of coupling coefficient, the corresponding coupling model is corrected for PBS. Considering the angle of the two Y-branch waveguides in PBS, the coupling length of 1430 um is figured out, which is different from that of 2186 μm without considering of the coupling in the Y branches in the previous design. And the simulation of the device performances are carried out by beam propagation method (BPM), the extinction ratio of the TE and TM mode is -26dB and -23dB, respectively.
