Abstract
A waveguide grating multifrequency receiver (MFR) is described with low polarization sensitivity. Polarization insensitivity is achieved using our polarization diversity scheme in which the TM polarized signal component of the unpolarized received input signal is converted to a second TE polarized signal and both TE polarized signals are made to share a common waveguide grating router and photodetectors. The MFR may be implemented using integrated optical preamplifiers and detectors in indium phosphide (InP).
