英文摘要 | PURPOSE:To make the thickness of a double hetero-structure section the most adequate by a method wherein the thickness of an active layer is set to be within the range where a specific condition toward a specific refractivity difference determined by refractivities of the active layer and a clad layer and an oscillating wavelength is satisfied. CONSTITUTION:A semiconductor laser device is provided with a double hetero- structure composed of an In(Ga1-XAlX) active layer 12 and two In(Ga1-YAlY)P clad layer (0, with reference to a specific refractivity difference, DELTA=(na-nc)2na, and an oscillating wavelength lambda is satisfied, and moreover it is more desirable that d is so set as to satisfy an equality, d/lambda 0.022DELTA. By these processes, the rise of the threshold current density can be limited to the extent which can be negligible, so that an InGaAlP semiconductor laser low in a threshold value can be realized. |
