摘要：

We propose a silicon polarization-diversity coherent receiver for wavelength-multiplexing transmission without using the large-footprint arrayed waveguide grating(AWG).We have integrated our proposed coherent receiver on the silicon-on-insulator(SOI) platform for high-capacity transmission.In the proposed coherent receiver,high-frequency photocurrent signals from other wavelengths are suppressed by electrical low-pass filters.Moreover,the signal-signal beat interference(SSBI) generated from each wavelength is eliminated by the balanced detection.These two features lend to the proposed coherent receiver being free of the mm-scale AWG.We have demonstrated our proposed coherent receiver to detect a 1.12-Tb/s wavelength-division-multiplexed and polarization-division-multiplexed 16-ary quadrature amplitude modulation(PDM-16-QAM) signal.The compact footprint of the silicon chip promises small-form-factor receivers for future ultra-high-capacity coherent communication systems that require a high integration level and low fabrication cost.
