英文摘要PURPOSE:To obtain a semiconductor laser having low aberration of laser light, low noise and high reliability, by providing at least a pair of layered dielectric films each of which has a specific refractive index, on each of two reflecting surfaces constituting an optical resonator. CONSTITUTION:An N-type Ga0.55Al0.45As clad layer 4 and a P-type GaAs cap layer 3 are provided on an N-type GaAs substrate 7, sequentially in that order, and a P-side electrode 8 and an N-side electrode 9 are formed. SiO2 is then provided on both the reflecting surfaces as first dielectric films. Amorphous Si films are formed thereon as second dielectric films. A quantum well layer is formed in stripes for transverse mode control in which five layers of Ga0.9 Al0.1As 5b and six layers of Ga0.7Al0.3As are layered alternately. The end faces on which the dielectric films are adhered have a reflectivity of about 40-85% as determined by a material used, producing conditions and thicknesses of the films. When the reflectivity is 50% or more, it has an effect of decreasing noise. According to this method, a semiconductor laser having low aberration of laser light, low noise and high reliability can be obtained.
