Hybrid electronic-photonic terahertz sources: direct injection locking of THz QC-laser from a Schottky diode multiplier
Perhaps the dominant source for single-frequency THz radiation below 1 THz is the Schottky diode frequency multiplier chain (FMC), in which the nonlinearity of a Schottky diode current-voltage relation is used to generate THz harmonics originating from microwave...
