We experimentally demonstrate a 40-channel 400 Gbps optical communication link utilizing wavelength division multiplexing and mode-division multiplexing. This link utilizes a novel 400 GHz photonic crystal resonator as a chip-scale frequency comb source. Silicon-on-insulator photonic inverse-designed 4×4 mode-division multiplexer structures enable a fourfold increase in data capacity. We show less than -10 dBm of optical receiver power for error-free data transmission using a PRBS31 pattern.
