Formation of sub-picosecond plasmon–polariton pulses via cooperative effects in a waveguide spaser

Abstract

The formation of surface plasmon–polariton pulses excited in a waveguide spaser during the collective decay of quantum dot excitons distributed in a dielectric layer near a metallic surface is considered. The waveguide spaser’s physical parameters and regimes of generation suitable for the formation of sub-picosecond plasmon–polariton pulses are determined with allowance for dissipative effects in the considered system.
