摘要： In a semiconductor laser 1, a current blocking layer 19 covers a p-type 2nd cladding layer 17 and a p-type cap layer 18 that extend in a lengthwise direction of an optical resonator, at both a light-emission end and an end opposite the light-emission end, to thus form non-current injection regions in an optical waveguide. By making current blocking layer 19 at the light-emission end large enough that carriers flowing from a current injection region do not reach the light-emission end surface, the light intensity distribution in the near field at the light-emission end surface is strongly concentrated, allowing the horizontal divergence angle of an emerging laser beam to be enlarged. This structure makes it possible to enlarge the horizontal divergence angle independently after having optimized the thickness of cladding layers and the size of the current injection region.
摘要翻译：在半导体激光器1中，电流阻挡层19覆盖在光谐振器的长度方向上延伸的p型2层包层17和p型覆盖层18，发光端和与发光端相对的端部，从而在光波导中形成非电流注入区域。通过使发光端处的电流阻挡层19足够大，使得从电流注入区域流动的载流子未到达发光端面，发光端面处的近场中的光强度分布被强烈集中允许出现的激光束的水平发散角被扩大。这种结构使得可以在优化包覆层的厚度和电流注入区域的尺寸之后独立地扩大水平发散角。
