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, a second waveguide, a third waveguide, a merging portion in which at least two waveguides of the first waveguide, the second waveguide, or the third waveguide merge, and an emission portion at one end of the merging portion. Each of the at least two waveguides includes a first portion that receives incident light and a second portion adjacent to the merging portion. The first portion has a greater width than the second portion.
Claims6
A light source module, comprising:
- a first light emitter configured to emit light with a first wavelength;
- a second light emitter configured to emit light with a second wavelength different from the first wavelength;
- a third light emitter configured to emit light with a third wavelength different from the first wavelength and the second wavelength;
- a cladding;
- and
- a core in the cladding, the core including
- a first waveguide configured to transmit light emitted from the first light emitter,
- a second waveguide configured to transmit light emitted from the second light emitter,
- a third waveguide configured to transmit light emitted from the third light emitter,
- a merging portion in which at least two waveguides of the first waveguide, the second waveguide, or the third waveguide merge, and
- an emission portion at one end of the merging portion,
- wherein each of the at least two waveguides includes a first portion configured to receive incident light and a second portion adjacent to the merging portion, and the first portion has a greater width than the second portion.
