摘要 |
An optical integrated circuit (21) is disclosed. The optical integrated circuit (21) includes: a dielectric waveguide (23) having at least a waveguide layer (4) for transmitting light in a first direction (8); a first reflector (14) for reflecting the light in a substantially opposite direction (13) to the first direction (8), the first reflector (14) being formed on an end face of the waveguide layer (4); a grating coupler (6) having a grating for diffracting at least a part of the light in a second direction (10) which is different from the first direction (8), the grating coupler (6) being formed at a surface (18) of the waveguide layer (4); and a light detector (22) for detecting the diffraction light (10, 11, 15, 16), the light detector (22) being optically connected with the dielectric waveguide (23). <IMAGE> |
