An MMI-based Polarization Splitter using Patterned Metal and Angled Joint



We have proposed a polarization beam splitter consisting of MMI with angled joint and metal layer made on an InP substrate. The total device length is less than 600 um. Computer simulation results show that the insertion loss is less than0.7 dB and the polarization extinction ratio is greater than 23 dB over the entire C-band.
