Efficient, broadband and compact metal grating couplers for silicon-on-insulator waveguides

Metal grating couplers for Silicon-on-Insulator waveguides are proposed. A silver grating coupler with 33% coupling efficiency is designed. A gold gating coupler prototype is fabricated using Focused Ion Beams demonstrating over 10% coupling efficiency. (C) 2007 Optical Society of Americ

Compact focusing grating couplers for silicon-on-insulator integrated circuits

Abstract—We report experimental results on compact and broadband focusing grating couplers, both in silicon-on-insulator (SOI) and gold on SOI. An eight-fold length reduction of the coupling structure from fiber to photonic wire in SOI, as com-pared to a linear grating and adiabatic taper, is obtained, without performance penalty. A proof of principle is given for a focusing grating coupler in gold on SOI, with 20 % fiber-to-focus efficiency.
