ABSTRACT:
An electron emitting element including a semiconductor opto-electronic layer having a split valence band and capable of emitting a beam of spin-polarized electrons from an emitting surface thereof upon incidence of an excitation laser radiation upon the emitting surface, and a reflecting mirror formed on one of opposite sides of the opto-electronic layer remote from the emitting surface and cooperating with the emitting surface to effect multiple reflection therebetween of the incident laser radiation. The emitting element may be provided with a semiconductor light modulator element for modulating the intensity of the laser radiation incident upon the opto-electronic layer. A laser source may be formed integrally with the emitting element and disposed on the side of the opto-electronic layer remote from the emitting surface.
