Enhanced Nonlinearities in Double-fishnet Negative-index Photonic Metamaterials
We numerically analyze the optical response and nonlinear susceptibilities of fishnet metamaterials with the holes infiltrated by a third-order nonlinear dielectric. Through full-wave simulations and employing a nonlinear parameter retrieval method, we confirm and quantify the enhanced nonlinearities, showing bulk third-order nonlinear susceptibilities that are up to two orders of magnitude lar...
متن کاملTheory of fishnet negative-index optical metamaterials.
We theoretically study fishnet metamaterials at optical frequencies. In contrast with earlier works, we provide a microscopic description by tracking the transversal and longitudinal flows of energy through the fishnet mesh composed of intersecting subwavelength plasmonic waveguides. The analysis is supported by a semianalytical model based on surface-plasmon coupled-mode equations, which provi...
متن کاملInfluence of the substrate on negative index fishnet metamaterials
Article history: Received 7 April 2010 Received in revised form 28 June 2010 Accepted 30 June 2010 We analyze numerically the influence of the dielectric substrate on the optical response and effective macroscopic parameters of fishnet metamaterials. We show that the substrate can suppress the region of the negative refractive index due to the weakening of the gap plasmon associated with the ma...
متن کاملConnected bulk negative index photonic metamaterials.
We show the designs of bulk one- and two-dimensionally isotropic photonic negative index metamaterials working around telecom wavelengths. The designed structures are inherently connected, which makes fabrication by direct laser writing and chemical vapor deposition or other techniques possible.
متن کاملUltrafast control of third-order optical nonlinearities in fishnet metamaterials
Nonlinear photonic nanostructures that allow efficient all-optical switching are considered to be a prospective platform for novel building blocks in photonics. We performed time-resolved measurements of the photoinduced transient third-order nonlinear optical response of a fishnet metamaterial. The mutual influence of two non-collinear pulses exciting the magnetic resonance of the metamaterial...
