Abstract A new type of cavity polariton, the optical Tamm state (OTS) polariton, is proposed to be realized by sandwiching a quantum well (QW) between a gold layer and a distributed Bragg reflector (DBR). It is shown that OTS polaritons can be generated from the strong couplings between the QW excitons and the free OTSs. In addition, if a second gold layer is introduced into the bottom of the DBR, two independent free OTSs can interact strongly with the QW excitons to produce extra OTS polaritons.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
