Abstract:
We present the design of a highly efficient polarization splitter-rotator that operates at both 1310- and 1550-nm wavelength bands in a 220-nm silicon-on-insulator platform. The proposed polarization splitter-rotator has a simulated insertion loss of −0.9 dB at 1310 nm and −1 dB at 1550 nm. This is the first theoretical demonstration of a biwavelength polarization splitterrotator. This letter is valuable for the implementation of a novel edge-coupling-based light duplexing silicon photonic system.
