An improved 1x4 MMI optical splitter is designed. Compared with an usual optical splitter, a smaller loss 0. 12dB and a better output port power uniformity 0.11dB are achieved for the optical signal transmission.展开更多

文摘In this paper, the multimode waveguide lengths and the output port locations of a SOI (silicon on insulator) material-based 1x4 MMI (multimode interference) optical splitter are optimized by means of FD-BPM (finite difference - beam propaga- tion method). An improved 1x4 MMI optical splitter is designed. Compared with an usual optical splitter, a smaller loss 0. 12dB and a better output port power uniformity 0.11dB are achieved for the optical signal transmission.
