Plasmon pulse generator of terahertz frequencies

FIELD: physics. SUBSTANCE: plasmon pulse generator of the terahertz frequency includes a spaser in the passive Q-switching mode based on the active medium placed in the resonant structure formed in a thin metal film, placed on the substrate, an active medium pumping means, an output means of the generated plasmon pulses. The resonant structure is a channel with a rounded bottom, in which the active medium is placed in the form of quantum dots. The active medium pumping means is in the form of the ultraviolet radiation source. Herewith one part of the quantum dots is open to the said radiation source, and the other part is shielded. EFFECT: providing the generation possibility of the optical plasmon pulses with the terahertz frequency and the subsequent integration possibility into the advanced plasmon circuits. 10 cl, 10 dwg
