Abstract
Light coupling into a sub-micrometer-thick waveguide is usually done throug h a grating coupler. Coupling efficiency is strongly enhanced by addition o f a mirror above the grating. This new kind of coupler can be designed to a chieve efficiencies as great as 80%. Numerical calculations for a high-angu lar-spread Gaussian incident beam are compared with experimental results ob tained for a standard silicon-on-insulator waveguide.
