Abstract
A light source module includes a first light emitter, a second light emitter, and a third light emitter each to emit light with a different wavelength, a cladding, and a core in the cladding. The core includes a first waveguide that transmits light emitted from the first light emitter, a second waveguide that transmits light emitted from the second light emitter, a third waveguide that transmits light emitted from the third light emitter, a first merging portion in which two waveguides of the first waveguide, the second waveguide, or the third waveguide merge, a second merging portion in which the first merging portion merges with a waveguide other than the two waveguides of the first waveguide, the second waveguide, or the third waveguide, and an emission portion at one end of the second merging portion.
