Controllable Tamm Plasmon Effect Designed by Admittance Loci

Abstract

Tamm plasmon is a plasmonic resonance happens at the boundary of photonic crystal and metal. In this work, a novel design tool based on admittance loci is proposed to demonstrate the relationship between Tamm plasmon structure and the corresponding resonance effect. The tunability of resonance wavelengths and the optimization of coupling efficiency are presented.
