摘要

A theory of grating-coupler-induced light emission from nonradiative two-dimensional plas- mon modes in single heterostructures is presented. The theory is evaluated by a model calculation of emission spectra assuming Al-xGa_1-xAs/GaAs single heterojunctions with a metallic (or dielectric) grating. It is shown that emission spectra depend strongly on the dielectric property of the layered structures modulated by the surface grating as well as the sheet conductivity of the grating.
