Grating Assisted Electromagnetic Emission from Magneto-Plasmon and Cyclotron Modes in Two-Dimensional Plasma Layer on GaAs

Abstract

In our paper [1], the spectrum of electromagnetic (EM) radiation from two-dimensional (2D) plasmons in GaAs/AIGaAs heterostructure with metal grating coupler was calculated in a strict EM approach. Using this approach, the full 2D plasmon resonance linewidth observed in experiments [2] was explained in [1] with plasmon radiative decay, 2D electron scattering, and dielectric losses in the heterostructure layers taken into consideration. It was shown in [1] that for the characteristic parameters of experiment [2] the plasmon radiative decay linewidth is two orders of magnitude larger than expected from the perturbation theory [3] and is roughly of the same value as the dissipative electron damping calculated with using the experimental value of electron scattering time.
