Abstract
An optical circuit includes a substrate, a waveguide, and a mirror. The substrate includes a first surface. The waveguide includes a first core. The first core is formed of a semiconductor material. The waveguide is over a first surface of the substrate. The mirror reflects light emitted from the waveguide in a direction away from the first surface of the substrate. The mirror is a concave mirror. The waveguide includes a region that functions as an SSC.
