Abstract
In this paper, formation of dark plasmon-soliton in a plasmonic photonic crystal fiber (PPCF) structure is predicted and analyzed by the use of the generalized nonlinear Schrodinger equation (GNLSE). Linear analysis of the plasmonic guided modes in the proposed structure offers a lower attenuation and dispersion values compared with the conventional core metallic fiber. Kerr coefficient of the silica background and the thermo-modulational nonlinearity of the gold are considered as the origins of nonlinear behavior. A delicate balance between normal dispersion and nonlinear characteristics of the structure provides the necessary condition for the formation of dark plasmon-soliton. Moreover, the thermo-modulational nonlinearity of metal is accompanied by the delayed propagation of the guided modes which is well justified throughout the simulations. Undistorted and time-delayed propagation of solitary plasmonic modes is a key point for the potential applications in the future all-optical devices, sensing platforms, and frequency conversion.
