Paper Abstract

We report on our recent progress in high-speed and large-capacity silicon-photonics-based integrated device technologies targeting large-capacity transmission in both datacom and telecom networks fields. A 70 Gbaud NRZ operation of all-silicon Mach–Zehnder modulator was demonstrated using forward-biased PIN diodes accompanied by passive equalizers. A clear optical eye opening was obtained owing to a broad electro-optic bandwidth of 37 GHz. We also successfully developed co-package-type 16-channels parallel silicon integrated transceivers and demonstrated simultaneous 400 Gbps operation. A novel demultiplexer capable to resolve phase-error-induced impairments is reported. With a simple control algorithm combining the heaters with monitored powers, crosstalks of as low as -58 to -49 dB have been obtained. This technology enabling temperature insensitivity and high yields drastically improves performance and cost of wavelength division multiplexing (WDM) transceivers.
