<P>PROBLEM TO BE SOLVED: To easily perform optical coupling with an optical waveguide formed on a substrate at a low optical loss even when there is an error in the outer diameter precision of an optical component. <P>SOLUTION: The laser source is formed by disposing a laser element 102 and a wavelength conversion element 104 which converts the wavelength of the laser light of the laser element 102 and emits it, on a substrate 101. A waveguide part 103 is formed on the substrate 101 by a photolithography process. The laser element 102 and the wavelength conversion element 104 are positioned by the waveguide part 103 and disposed on the substrate 101. The laser light of the laser element 102, after guiding the waveguide part 103, enters the wavelength conversion element 104. <P>COPYRIGHT: (C)2013,JPO&INPIT |
