All-angle negative refraction in gain assisted Metallo- Semiconductor Photonic Crystal for visible light: Effect of plasmonic metals and nano-photonic device application

Abstract

All-angle negative refraction (AANR) in a gain assisted Metallo-Semiconductor Photonic Crystal (MSPC) for visible light with effect of different plasmonic (Al, Ag, Au, Cu) nanorod inclusion, is demonstrated. Proposed structure provides negative real values of both permeability (μ) and permittivity (ε) and extremely low imaginary values for visible light. Phase slope and phase velocity is shown to be negative for blue light for proposed Left-Handed structure. A comparison of dispersion properties and left-handed resonance for different plasmonic nanocomposites of a similar shape and geometry shows permittivity-dependent dispersion and resonant properties. Extremely high Left-Handed Transmission Efficiency (≫99%) are also investigated. Demonstration of near and far-field resonance patterns reveal the nano-photonic device applications potential.
