We demonstrate a 10 wavelength, 200 GHz spaced, monolithically integrated, polarization-multiplexed, InP differential quadrature phase shift keying receiver operating at 45.6 Gb/s per wavelength. The receiver is based on a novel technique for polarization demodulation and phase tracking that does not require any external components.
