Systems and methods are provided for receiving an optical signal from an optical fiber, including: coupling via an optical coupler the optical signal from an optical fiber into first and second waveguides, wherein the optical signal comprises TE and TM polarized optical signals and the optical coupler couples the TE polarized optical signal into the first waveguide and the TM polarized optical signal into the second waveguide; equalizing the TE and TM polarized optical signals from the coupler to equalize optical power levels of the TE and TM polarized optical signals; optically combining the equalized TE and TM polarized optical signals; and transmitting the combined optical signal to a photodetector.
