Polarized Tamm plasmon laser

Plasmonic Tamm states are interface modes formed at the boundary between a distributed Bragg mirror and a metallic layer. Their optical properties lie in between surface plasmons and microcavity photonic modes. In particular, the losses are reduced compared to a conventional plasmon. We will describe some features of semiconductor quantum wells coupled to extended Tamm modes, like strong coupling with the excitons and lasing. The main advantage of the Tamm modes lies in the easy confinement of the mode which can be obtained only by structuring the metallic part of the structure.
