Abstract
An apparatus and method for tunable generation of terahertz waves at room temperatures are provided. The apparatus for tunable terahertz generation comprises: (A) a terahertz antenna further comprising a magnon gain medium; (B) a means for generating the nonequilibrium magnons in the magnon gain medium; wherein the terahertz antenna is configured to emit generated terahertz photons; and (C) a means for tuning frequency of terahertz photons emitted by the terahertz antenna. The magnon gain medium is selected from the group consisting of: {a ferromagnetic semiconductor; a dilute magnetic semiconductor (DMS); a half-metallic ferromagnet (HMF); and a ferromagnetic conductor, with a gap in the density of states of the minority electrons around the Fermi energy}.
