<p>A laser light source comprises, a substrate (1), a channel waveguide path (2) formed on said substrate (1) 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 (6) formed on the substrate (1), and an extracting structure for extracting the laser beam generated in the channel waveguide path (2) to the slab waveguide path (6) as a beam collimated in one direction.</p> |
