Abstract
According to one embodiment, a light source includes a plurality of light-emitting elements each including one or more surface-emitting lasers; and a plurality of detecting elements located on a same substrate as the light-emitting elements. The detecting elements individually detect quantities of output light of the light-emitting elements.
Claims15
A light source comprising:
- a plurality of light-emitting elements each comprising one or more surface-emitting lasers;
- and
- one or more detecting elements located on a same substrate as the light-emitting elements, the one or more detecting elements to detect quantities of output light of the light-emitting elements,
- the light-emitting elements and the one or more detecting elements include a waveguide formed on the same substrate,
- wherein:
- the waveguide is to guide light from the light-emitting elements to the one or more detecting elements,
- the one or more detecting elements receive light from the light-emitting elements through the waveguide, and
- a region which the waveguide is absent from exists in-between the light-emitting elements and the one or more detecting elements.
