Abstract
An apparatus for tunable generation of terahertz photons is provided. The apparatus comprises a three level magnon laser, an injection means, a terahertz antenna, and a tuning means. The terahertz antenna further comprises a magnon gain medium that supports generation of nonequilibrium magnons. 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.
