Abstract—We report our recent work on wavelength-agile silicon photonic integrated circuit for low-cost optical receiver, which includes a monolithic integrated germanium p-i-n photodetector and a tunable filter. The circuit is fabricated using standard CMOS technology on SOI platform, paving the way for further integration with more optical building blocks and CMOS transistor circuits. The wavelength tuning range of the integrated circuit is ~11.5nm along with the tuning speed of less than 400μs. The tuning efficiency is ~0.16nm/mw. The measured fiber-to-PD responsivity of the photonic integrated circuit is ~0.10A/W. A photonics packaging structure for the silicon PIC is also proposed.
