ABSTRACT:
A solid state source of radiant energy having a characteristic frequency spectra with a high frequency cutoff .nu..sub.co, which is a function of the applied voltage value. The source is a metal-insulator-metal tunnel junction wherein the insulator layer is relatively thin with respect to the metal layers and inelastic tunneling occurs. To facilitate output coupling to surface plasmon modes in the junction, the counter-electrode metal layer, from which the radiant energy is emitted, is roughened.
