- Abstract
- We experimentally demonstrate temperature-tuned and gain-assisted surface-plasmonic coherent perfect absorbers. In these devices, coherent perfect absorption (CPA) is supported by balancing the absorber's radiative and non-radiative decay rates under thermal tuning of free-electron collision frequency in the Ag layer and optical tuning of the amplification rate in the adjacent dielectric film with optical gain, respectively. The results show that these methods are experimentally feasible and applicable to various CPA configurations. (C) 2015 Optical Society of America
