英文摘要 | PURPOSE:To obtain fundamental transverse mode oscillation up to a high-current region at a low threshold by forming AlGaAs growth block layers for AlGaAs layers on both sides that shape an active region and bending an active region section in an active layer. CONSTITUTION:An active layer 4 is bent on a current inrush region to a V-shaped etching section 7 by an AlGaAs growth block layer 1 Consequently, inrush currents concentrically flow only into a bent active region 8, and both sides of the active region 8 are also held by an N-type AlGaAs upper clad layer 5 having a small refractive index, and the effect of current confinement in the lateral direction and light is also displayed. Since the forbidden band zone of the AlGaAs growth block layer 11 is widened, the layer 11 also functions as a current block layer effectively. Accordingly, light and currents are confined effectually by the active region 8, thus acquiring a laser having a fundamental transfers mode stable up to a high current inrush region by low threshold currents. |
