英文摘要 | An InGaAlN-based semiconductor laser device, comprising a first layer of a first conductivity type, an active layer having a smaller forbidden band than that of the first layer, and a second layer of a second conductivity type having a larger forbidden band than that of the active layer. The second layer includes a flat region and a stripe-shaped projecting structure. A stripe-shaped optical waveguide forming layer of the second conductivity type having a larger refractive index than that of the second layer is formed on the stripe-shaped projecting structure. A current-constricting layer of the first conductivity type or of a high resistance is formed for covering a top surface of the flat region of the second layer, a side surface of the projecting structure of the second layer, and a side surface of the optical waveguide forming layer. A difference between a thermal expansion coefficient of the current-constricting layer and a thermal expansion coefficient of the second layer is in the range of -4 × 10-9/°C to +4 x 10-9/°C. |
