A 4-Lane 400 Gb/s Silicon Photonic Transceiver for Intra-Datacenter Optical Interconnects

We present a four-lane silicon photonic transceiver for intra-datacenter optical interconnects. A net rate of 400 Gb/s is achieved at a bit error rate below the KP-4 forward error correction threshold of 2.4 × 10 −4 .
