摘要	PURPOSE:To contrive improvement in the stability of an oscillation axial mode by a method wherein the surface of a resonator is formed on the terminal of a smoothly branched waveguide path by the difference in the effective index of refraction based on the difference of the light absorption by a substrate between the inside and the outside of the channel formed on the substrate. CONSTITUTION:The lateral mode condition of the two waveguide paths determined by the main channel part 19 and the sub-channel part 22 fluctuates by the presence of optical coupling. However, in either case, the resonator which is determined by a branched waveguide path is formed inside. To be more precise, the difference DELTAn of effective index of refraction based on the light absorption of a substrate is generated between the inside and the outside of a groove on the terminal part of the sub-channel part 22, the reflection of a laser beam is generated by said difference of effective index of refraction, and a resonant surface is formed. The semiconductor laser device having stable axial mode characteristics can be obtained by the above-mentioned interference effect.
其他摘要	目的：通过一种方法改进振荡轴模的稳定性，其中谐振器的表面由光吸收差异引起的有效折射率差异形成在平滑分支的波导路径的末端上通过在衬底上形成的沟道的内部和外部之间的衬底。组成：由主通道部分19和子通道部分22确定的两个波导路径的横向模式条件由于光耦合的存在而波动。然而，在任何一种情况下，由分支波导路径确定的谐振器形成在内部。更准确地说，在子通道部分22的末端部分上的凹槽的内部和外部之间产生基于基板的光吸收的有效折射率差ΔΔ，激光束的反射由有效折射率的所述差异产生，并且形成共振表面。通过上述干涉效应可以获得具有稳定轴模特性的半导体激光器件。
