Abstract
The present invention relates to a semiconductor laser having light emitting wavelengths from blue to UV, more specifically a semiconductor laser which can form a laser resonator by perpendicular cleavage of the substrate and a method for fabricating the semiconductor laser. The semiconductor laser comprises a single crystal substrate 10 of cubic system, and an epitaxial crystal layer 12 with the laser resonator formed by cleavage planes 30 thereof. Cleavage planes 28 of the single crystal substrate 10 and the cleavage planes 30 of the epitaxial crystal layer 12 are not parallel with each other, and the intersection between the cleavage planes 30 of the epitaxial crystal layer 12 and the surface of the single crystal substrate substantially agrees with the intersection L between the cleavage planes 28 of the single crystal substrate 10 and the surface of the single crystal substrate 10.
