Title: OPTICAL CIRCUIT AND OPTICAL DEVICE
Abstract:
An optical circuit (10) is provided with a substrate (100), a waveguide (202), and a mirror (312). The substrate (100) has a first surface (102). The waveguide (202) has a first core (212). The first core (212) is formed of a semiconductor material. The waveguide (202) is on the first surface (102) of the substrate (100). The mirror (312) reflects light in the direction of being separated from the first surface (102) of the substrate (100), said light having been outputted from the waveguide (202). The mirror (312) is a concave mirror. The waveguide (202) has a region that functions as a spot-size converter (SSC) (214).
