摘要： A semiconductor light source includes an active layer oscillating a semiconductor laser light. The grating device includes a ridge type optical waveguide comprising an incident face to which said semiconductor laser light is made incident and an emitting face for emitting an emitted light having a desired wavelength, a Bragg grating comprising convexes and concaves and formed in said ridge type optical waveguide, and an emitting side propagating portion disposed between the incident face and said Bragg grating. The system oscillates the laser in a reflection wavelength range of said Bragg grating. A width of the optical waveguide in the Bragg grating and a width of the optical waveguide at the emitting face are different from each other.
