Patent

CA 2104278

An optical integrated circuit is disclosed. The optical integrated circuit includes: a dielectric waveguide having at least a waveguide layer for trans- mitting light in a first direction; a first reflector for reflecting the light in a substantially opposite direction to the first direction, the first reflector being formed on an end face of the waveguide layer; a grating coupler having a grating for diffracting at least a part of the light in a second direction which is different from the first direction, the grating coupler being formed at a surface of the waveguide layer; and a light detector for detecting the diffract- ed light, the light detector being optically connected with the dielectric waveguide.
