A silicon photonic 8λ, x 32Gbps/λ, WDM transceiver with integrated laser array and SOA for optical I/O

We demonstrate a 256Gbps WDM transceiver with eight 200GHz-spaced wavelengths simultaneously modulated at 32Gbps and <1e-12 BER. The system includes a silicon photonic PIC with integrated lasers, microring modulators, SOAs, Ge photodetectors, and a co-designed CMOS EIC.
