InP-based photonic integrated circuits

Semiconductor photonic integrated circuits (PICs) refer to that subset of optoelectronic integrated circuits (OEICs) which focus primarily on the monolithic integration of optically interconnected guided-wave optoelectronic devices. PIC research is driven primarily by the high cost of single-mode optical connections, but it has also been given new vitality from advances in MOVPE crystal growth and related processing techniques. Design issues and recent progress in the fabrication and performance of InP-based PICs is discussed.
