Abstract
A quite small device producing blue light with small loss of light. The device has a laminated laser light-emitting portion and an optical waveguide for second-harmonic generation. Both light-emitting portion and waveguide are formed on the same semiconductor substrate. The waveguide takes the form of a thin laminated layer. The laser light-emitting portion and the waveguide are substantially flush with each other.
