Publikováno v: New Journal of Physics, Vol 18, Iss 8, p 083018 (2016)

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 semicond
