We realized a monolithic polarization-diversity dual-quadrature coherent receiver with on-chip balanced detection in a silicon photonic integrated circuit with integrated germanium detectors. We tested it using a polarization-division multiplexed quadrature phase-shift keyed signal at 112-Gb/s.
We demonstrate the real-time implementation of a FPGA-based coherent optical OFDM (CO-OFDM) receiver at 2.5-G samples/s, which successfully receives a subband of a 54-Gb/s multi-band CO-OFDM signal with a record-low error floor of 3.7 times 10-8.
DSP-based coherent optical communication systems have gained tremendous interest in recent years. While most experiments were performed using offline processing, some effects can only be observed using real-time processing.
