A multi-layered split ring metamaterial for a multiwavelength and tunable lasing spaser. Journal of Optics, 14(4).||Series/Report no.:||Journal of optics||Abstract:||We report a multiwavelength and tunable lasing spaser realized by a gain-assisted metamaterial. The metamaterial consists of three regularly spaced parallel arrays of weakly asymmetric metallic split rings, with the first-layered array located on the gain medium surface and the other two-layered arrays embedded in it. Our simulations demonstrate that the three-layered metamaterial can radiate three-wavelength electromagnetic waves with high Q factors and transmission enhancement, which can be tuned by varying the gain coefficient.||URI:||https://hdl.handle.net/10356/95845
