Monolithic Silicon Chip with 10 Modulator Channels at 25 Gbps and 100-GHz Spacing

Abstract

We demonstrate a chip containing ten low-chirp silicon modulators, each operating at 25 Gbps, multiplexed by a SiN arrayed-waveguide grating with 100-GHz spacing, showing the potential for 250 Gbps aggregated capacity on a 5×8 mm2 footprint.
