Title: Semiconductor laser device
Inventor: SHIOZAWA HIDEO
IPC: H01S5/343
Filed: 2000-07-06
Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing cost and further to suppress spreading of the spreading angle of a beam in vertical direction in a device in which lasers of different wavelength bands are monolithically integrated. SOLUTION: The well layers 151 of a multiple quantum-well active layer 104 are formed with a GaAlAs-based semiconductor material, while the barrier layers 152 are formed with GaAlAs, and the cladding layers 102, 106 are formed with In(Ga1-x-Alx)P (0<=x<=1). As a consequence, expansion of the spreading angle of the light beam is suppressed. Besides, bandgap difference between the clad layers and the active layer is expanded. Therefore, during the laser operation, leakage of electrons from the active layer to the clad layers is suppressed, and the temperature characteristics are improved. Furthermore, carriers are injected into well layers uniformly, and the voltage lowering is suppressed.  In addition, since light-guiding layers 103, 105 composed of In(Ga1-yAly)P (0<=y<=1) are formed between the active layer 104 and the clad layers 102, 106, diffusion of the dopants for the material composing the clad layers into the active layer is prevented, resulting in enhancement of the device reliability.
