Monolithic Microring-based WDM Optical I/O for Heterogeneous Computing

Abstract

For the first time, we demonstrate an error-free, 128Gbps (8x16Gbps) optical transceiver using a microring-based wavelength-division multiplexed (WDM) architecture. The optical transceiver ran for 12 hours with zero errors, resulting in a measured bit-error rate of <1.45e-15 per optical lane. The total number of bits sent during this time was ~691 terabits per lane and ~5.5 petabits aggregate across all lanes.
