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 *** the proposed coherent receiver,high-frequency photocurrent signals from other wavelengths are suppressed by electrical low-pass ***,the signal-signal beat interference(SSBI) generated from each wavelength is eliminated by the balanced *** two features lend to the proposed coherent receiver being free of the mm-scale *** have demonstrated our proposed coherent receiver to detect a 1.1.-Tb/s wavelength-division-multiplexed and polarization-division-multiplexed 1.-ary quadrature amplitude modulation(PDM-1.-QAM) *** compact footprint of the silicon chip promises small-form-factor receivers for future ultra-high-capacity coherent communication {1. that require a high integration level and low fabrication cost.
We propose a mode-division-multiplexing (MDM) self-homodyne coherent system over weakly-coupled multiple-ring-core 1.-mode fibre and experimentally demonstrate single-core 7.2-Tb/s (5.64-Tb/s net rate) transmission wi...
