High-Temperature Operation of Chip-Scale Silicon-Photonic Transceiver

A chip-scale optical transceiver was developed based on silicon photonics technology and optical/electrical assembly for 25-Gbs× four-channel applications. Optical transmitters and receivers were integrated on a single silicon platform enabled by the hybrid integration of a quantum-dot laser diode, optical pins, and a 28-nm CMOS based electrical IC. Temperature compensation functions were implemented in a modulator driver and a transimpedance amplifier for high-temperature operations. The functions allowed us to successfully demonstrate error-free 25 Gb/s × four -channel data transmission at 85°C.
