High-performance silicon photonics platform for low-power photonic integrated circuits

High-performance Silicon photonics platform based on an advanced Si CMOS technology is a key to produce low-power integrated photonic chips for the optical interconnect in data transmission. The state-of-the-art Silicon photonics technology has been developed by using 40 nm CMOS technology. Key features are highly reproducible optical devices and high-quality epitaxial growth Ge for photodetectors. PIN-diode-based Si modulators and PN-type Ge detectors were demonstrated at 25Gbps operation at 1.3-1.5 um wavelength.
