Patent abstract
Provided is an optical splitter circuit capable of solving a problem that stability of an optical splitting ratio is low. An optical splitter 201 splits an input light beam. Arm waveguides 202 and 203 each have a width that decreases in a direction in which a light beam propagates and a tapered structure that propagates the light beam split by the optical splitter 201. Taper angles of these tapered structures differ from each other. The optical multiplexer 204 multiplexes the light beams from the arm waveguides 202 and 203 and then outputs them.
