摘要 | PURPOSE:To simplify the structure of the lateral-mode controlled InGaA P semiconductor laser of the title device and improve the yield of the laser by incorporating a diffraction grating in the laser. CONSTITUTION:An n-GaAs substrate 10, n-In0.5(Ga0.3A0.7)0.5P clad layer 11, non- doped lnGaP active layer 12, p-In0.5(Ga0.7A0.3)0.5P optical waveguide layer 13, current blocking layer 14, p-In0.5(Ga0.3A0.7)0.5P clad layer 15, p-GaAs contact layer 16, and diffraction grating 17 are provided. Since the built in diffraction grating 17 amplifies only rays of light in the direction of a resonator, a lateral- mode controlled laser which stably oscillates in a single longitudinal mode can be obtained. Therefore, a laser which is simple in structure and has good characteristics can be obtained in high yield. |
其他摘要 | 目的:简化标题装置的横模控制InGaA P半导体激光器的结构,并通过在激光器中加入衍射光栅来提高激光器的产量。组成:n-GaAs衬底10,n-In0.5(Ga0.3A0.7)0.5P覆层11,非掺杂lnGaP有源层12,p-In0.5(Ga0.7A0.3)0.5P光学提供波导层13,电流阻挡层14,p-In0.5(Ga0.3A0.7)0.5P包层15,p-GaAs接触层16和衍射光栅17。由于内置衍射光栅17仅在谐振器的方向上放大光线,因此可以获得以单纵模稳定振荡的横向模式控制激光器。因此,可以以高产率获得结构简单且具有良好特性的激光器。 |
