Abstract
Problem formulating. Lasing on strong («radiative») plasmon resonance mode in graphene structure with dual grating gate with asymmetric unit cell requires strong gain. It is possible to achieve lasing in a weak ("non-radiative") mode at a lower gain rate. Goal. Theoretical study of laser generation on weak plasmonic resonance mode in single layer graphene structure screened by dual grating gate with asymmetric unit cell. Result. Laser generation on weak plasmonic resonance mode in single layer graphene structure screened by dual grating gate with asymmetric unit cell is reached. Excitation of a weak plasmon resonance mode requires less gain than excitation of a radiative one. Practical meaning. Results can be used to create sources of terahertz waves.
