As electrodes on the side of a reflecting film 3, a central electrode 7 and a circumferential electrode 8 are formed directly above an active layer 4 by using an AuZn/Au multilayer film. For example, when a current is made to flow across a central electrode 7 and a substrate-side electrode 6 and, at the same wime, a current is made to flow across one circumferential electrode 80 and the substrate-side electrode 6, the polarization direction of the emitted beam of light can be controlled in a direction in which the central electrode 7 is connected to the center of the circumferential electrode 80. Consequently, a polarizing face can be decided in a prescribed direction in a surface emitting semiconductor laser, and the polarizing face can be changed to an arbitrary direction when it is controlled electrically.
