Abstract

Abstract: In this paper, we characterize the electric field distribution of confined optical modes in a 0D Tamm structure, consisting in a metallic disk deposited on a Bragg mirror. The modes are probed at room temperature, through the fluorescence of semiconductor colloidal nanocrystals. We perform a combined analysis of the resonant modes distribution in both direct space and Fourier space and show, in good agreement with numerical simulations, that a subportion of the structure will radiate with a different angular distribution depending on its position. Such analysis is shown to probe the gradient of the phase of the confined optical modes.
