Confined Visible Optical Tamm States
Résumé
Optical Tamm states are 2D electromagnetic modes propagating at the interface between a Bragg mirror and a metallic film. When a thin (a few tens nm) metallic micron—radius disk is deposited on a Bragg mirror, optical Tamm states can be confined below the disk surface, creating a Tamm-states cavity. We describe here the photoluminescence properties of colloidal semiconductor nanocrystals embedded in a Tamm cavity. Tamm states confinement effects are demonstrated and analysed as a function of the disk diameter, and compared with finite-elements simulations.
