| 英文摘要 | 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. |
