Abstract :
We propose and fabricate a silicon based polarization insensitive scheme consisting of a micro ring resonator and two 2-dimensional grating couplers. For demonstration, simultaneous demodulation for WDM-PDM NRZ-DPSK signals has been achieved successfully with error free, reflecting the good performance and the practicability of the proposed scheme.
