英文摘要 | PURPOSE:To reduce oscillating threshold currents, and to obtain excellent high- output characteristics by arranging a current constriction function and an index waveguide function so as to hold an active layer from upper and lower sections, separately constituting each function and forming a narrow current path. CONSTITUTION:A P type GaAs buffer layer 2 and an N type GaAs current constriction layer 3 are shaped onto a P type GaAs substrate 1 in succession through a crystal growth process, thus constituting a first crystal laminate. A groove reaching the layer 2 is shaped. A P type GlGaAs layer 4, an AlGaAs layer 5 as an active layer, an N type AlGaAs layer 6 and an N type AlGaAs layer 7 are formed successively, thus constituting a second crystal laminate. A groove reaching the layer 6 is shaped. An N type AlGaAs layer 8 and an N type GaAs layer 9 are formed. According to the constitution, a current constriction function and an index waveguide function are isolated severally, and wide index waveguide structure can be shaped though a narrow current path is formed, thus improving high-output characteristics while acquiring characteristics having a little coherence. |
