Abstract
We have used the finite element method to demonstrate numerically that losses in Tamm plasmon structures can be reduced, and Tamm resonance parameters can be tuned using a sub-wavelength ring-shaped structuration of the metal layer. The axisymmetric structure consists of a GaAs/Al0.95Ga0.05As Bragg reflector covered with a sub-wavelength ring. The results demonstrate that the quality factor of the Tamm plasmon mode with a ring of given parameters increases substantially. In addition, we have compared the properties of the structure with two different resist materials (PMMA and CSAR 62) and demonstrated a shift in the resonance frequency of the Tamm plasmon mode for each case.
