Abstract
The invention provides a solution for the full integration of a coherent receiver on Indium Phosphide (InP) or other material that has a number of advantages over current coherent receiver design. PIN waveguides can be reverse biased and forward biased to modify the mode effective index so as to realize an integrated polarization beam splitting function and the 90 degree optical hybrid. The fabrication tolerance is therefore greatly increased; resulting in much reduced complexity and cost for the final receiver.
