Tamm surface plasmon laser

Plasmonic Tamm states are interface modes formed at the boundary between a photonic structure and a metallic layer. These modes present both the advantages of surface plasmons and of microcavities photonic modes. Tamm plasmons can be spatially confined by structuring the metallic part of the system, thus reducing the size of the mode and allowing various geometries. They are very good candidates for optimizing the emission properties of semiconductor nanostructures. Recently the extraction of single photons emitted by a quantum box has been evidenced in a Tamm Plasmon structure. Due to the relatively low damping and the versatility of the Tamm geometries, these modes are also good candidates for new type of lasers.
