Abstract
A semiconductor chip provides an optical medium for light propagation. The semiconductor chip includes a chip surface with an outer perimeter and a cavity in the chip surface. The cavity includes a peripheral wall and a bottom surface surrounded by the peripheral wall, the bottom surface adiabatically couplable to an optical waveguide. The cavity is located at an area of the chip surface spaced from the outer perimeter thereof.
