    • A semiconductor laser device that can be operated at high power and that has a structure which can suppress kink, reduce loss and stabilize the direction of polarization simultaneously, and in which an optical pattern decreases monotonously as receding from an active layer and the crystal composition can be easily controlled. A plurality of layers of high refractive index different in the composition from that of the cladding layer are introduced being dispersed over a range wider than the spot size for directing light closer to the lower cladding layer of the semiconductor laser and stabilizing the direction of polarization. The electric field intensity is decreased monotonously as receding from the active layer for the optical pattern.
    • 一种半导体激光器件,其能够以高功率工作,并且具有能够同时抑制扭结,减少损耗和稳定偏振方向的结构,并且其中光学图案随着从有源层退出而单调减小,并且晶体组成可以 易于控制。 引入组成不同于包覆层的多个高折射率层,其分散在比用于引导光更靠近半导体激光器的下包层并稳定偏振方向的光斑尺寸的范围内。 随着从光学图案的有源层退出,电场强度单调减小。
