Tóm tắt

Optical Tamm structures have potential for the development of optoelectronic devices, provided they overcome the challenge of low-quality factor of modes and inherent losses associated with plasmonic metal films. In this work, we present lasing in a super-Tamm structure consisting of a silver thin film deposited on a 4-(dicyanomethylene)-2-methyl-6-(4- dimethylaminostyryl)-H-pyran (DCM) dye-doped polyvinyl alcohol (PVA) spacer layer coated on a SiO
