Excitation of electron emission from optical glass surface with waveguide radiation

The surface emission effects are investigated for optical waveguides, formed on the basis of K8 glass with a low temperature ion exchange treatment. As a result of the experiments performed it is proved the possibility of exciting nonstationary electron emission from the surface of gradient planar waveguides under the action of intrinsic radiation of the waveguide. The emission selection effect for guide wave modes is discover. It consists of electron-emission mode spectrum dependence on preliminary excitation of fixed order mode.
