Abstract
An optical chip comprises an input edge coupler having at least one input waveguide and configured to receive light on two orthogonal modes of same polarization, a demultiplexer configured to divide the two orthogonal modes into a mode carried on a first intermediate waveguide and a mode carried on a second intermediate waveguide independent from the first intermediate waveguide, a polarization multiplexer configured to recombine the modes carried on the intermediate waveguides into two polarization-orthogonal modes carried on one output waveguide.
