英文摘要PURPOSE:To reduce the astigmatic difference by providing a P-type GaAs light- absorbing layer between an N-type GaAs current constriction layer and a P-type GaAlAs cladding layer. CONSTITUTION:On a P-type GaAs substrate 11, an N-type GaAs current constriction layer 12a, a P-type GaAs light-absorbing layer 12b, a P-type GaAlAs cladding layer 13, a P-type GaAlAs active layer 14, an N-type GaAlAs cladding layer 15, and an N-type GaAs cap layer 16 are laminated by liquid -phase growth or vapor deposition technique. Accordingly, even if the laser, for example, of 870nm wavelength is fabricated, the light generated in the P-type GaAlAs active layer 14 is more absorbed in the P-type GaAs light-absorbing layer 12b and the effective difference in refractive index also in a direction parallel to a P-N junction. Then, the enhancement of the astigmatic difference can be prevented.
