(a) Schematic representation of the sample evidencing the DBR, the PMMA resist layer (e = 35 nm) and the 45 nm silver layer. Rings of inner diameter din and arm width L are defined in the PMMA layer. (b) Experimental emission dispersion relation recorded on a ring of inner diameter din = 6 µm. (c) Wavelength-resolved emission as a function of the position along the diameter of the ring.
