摘要: In this paper, we realized a monolithic silicon photonic integrated circuit (PIC) for polarization and phase diversity coherent detection. The PIC includes two beam splitters, 90° optical hybrids, four pairs of balanced photodiodes implemented as germanium detectors. We tested the using polarization-division multiplexed quadrature phase-shift keyed signals at 43 112 Gb/s.
