ABSTRACT:
A semiconductor device of a filamentary laser is fabricated by a method including the steps of forming a first GaAlAs layer on a GaAs body, forming a laser active layer of GaAs on the first GaAlAs layer, etching the first GaAlAs layer and the laser active layer so as to have a mesa shaped structure and to expose the GaAs body, and forming a second GaAlAs layer on said exposed GaAs body and on the surface of said mesa shaped structure so that the mesa etched first GaAlAs layer and the mesa etched active layer are surrounded by the second GaAlAs layer.
