ABSTRACT:
An apparatus and method for generating modulated terahertz radiation are provided. The apparatus comprises: (A) a means for generating Terahertz radiation by pumping nonequilibrium electrons into Magnon Gain Medium (MGM); wherein the nonequilibrium electrons emit nonequilibrium magnons, and wherein interaction between nonequilibrium magnons in the Magnon Gain Medium (MGM) causes generation of Terahertz radiation; and (B) a means for modulating the generated Terahertz radiation. The modulating means further comprises: an AC magnetic field generator, or an AC electric field generator.
