Simple to fabricate and highly efficient spot-size converters
III-V Semiconductor Photonic ICs
Main Researcher: Wouter D'Oosterlinck
There are two rationales for the use of integrated spot-size converters (SSC): 1) fiber coupling and pigtailing of photonic integrated circuits (PIC), and 2) hybrid integration of lasers, semiconductor optical amplifiers and other PIC’s with low-loss silica on silicon planar circuits. We investigate SSC’s that are based on a tapered active region and an underlying passive guide. Simple to fabricate and highly efficient SSC’s have been developed.
