ABSTRACT:
A semiconductor laser for use as a bistable optical device in which an active semiconductor layer has corrugations of predetermined pitch on its surface and a semiconductor optical waveguide is formed on the corrugation. At least one end of the active layer is exposed at an oblique angle so that light in the active layer propagating along the direction of corrugation is reflected from the oblique face to a normal of the surface of the laser. Electrodes are provided above and below the active layer.
