ABSTRACT:
A laser light source comprises, a substrate, a channel waveguide path formed on said substrate and having an active area for generating a laser beam upon reception of energy, so as to constitute a laser resonator, a device for supplying the energy to the active area, a slab waveguide path formed on the substrate, and an extracting structure for extracting the laser beam generated in the channel waveguide path to the slab waveguide path as a beam collimated in one direction.
