摘要	PURPOSE:To realize a high conversion efficiency by disposing an optical waveguide having a light radiating function and other optical waveguide in the same plane, forming laser resonators including the two waveguides, and optically coupling the adjacent laser resonators. CONSTITUTION:A laser oscillator 101 formed on an N-type GaAs substrate has 10 lasers having the same characteristics and disposed in parallel with each other. All the oscillators are optically coupled through a light confinement dielectric unit 103. The ten laser lights all have the same phase by the optical coupling. A SHG optical waveguide 102 is disposed on the extension line of the laser light, and disposed in the same plane as that of the laser resonator. SHG is generated in the waveguide 102. The thickness of the waveguide 102 is regulated to align the positions of the laser light and the SHG light. Further, since the waveguide 102 is optically coupled with the adjacent waveguide, the generated ten SHG lights have the same phase, and can be operated as one luminous flux in practice.
其他摘要	目的：通过在同一平面上设置具有发光功能的光波导和其它光波导，实现高转换效率，形成包括两个波导的激光谐振器，并且光耦合相邻的激光谐振器。构成：形成在N型GaAs衬底上的激光振荡器101具有10个具有相同特性并彼此平行设置的激光器。所有的振荡器都通过光限制介质单元103光耦合。十个激光都通过光耦合具有相同的相位。SHG光波导102设置在激光的延长线上，并设置在与激光谐振器相同的平面内。在波导102中产生SHG。调节波导102的厚度以对齐激光和SHG光的位置。此外，由于波导102与相邻的波导光耦合，所产生的十个SHG光具有相同的相位，并且在实践中可以作为一个光通量工作。
