From: Spatially uniform enhancement of single quantum dot emission using plasmonic grating decoupler
(a) 2D-LDOS calculated inside a gold grating for different widths of the ridges. LDOS is shown in the range of wave vectors from 0.9 to 1.2 where the dominant peak due to coupling to SPPs observed. (b,c) Calculated radiative decay rate enhancement as a function of position for randomly oriented QD inside the cavity for different gold (b) or silver (c) SPP grating width w. Radiative decay rates are normalized with respect to the radiative decay rate obtained on a bare metal film.
