Abstract: An optical coupler of the present disclosure includes a plurality of one-input multiple-output multimode interference input parts provided for each laser beam of the plurality of laser light beams. The optical coupler further includes one light output port configured to allow three laser light beams to be coupled and emitted therethrough, a plurality of light input side optical waveguides configured to extend from each of the plurality of one-input multiple-output multimode interference input parts, a light output side optical waveguide configured to extend from the light output port, and an optical coupling part configured to have the plurality of light input side optical waveguides and the light output side optical waveguide connected thereto.
