Abstract

The mode characteristics (dispersion relation and Q factor) of metal-coated microcylinders are achieved from the analytical resonance eigenequation. Among the resonance modes, two surface plasmon polariton (SPP) modes have completely different characteristics compared to the hybrid plasmonic whispering gallery modes (WGMs). In the metal-coated microcylinder, the Q factor of the asymmetrical SPP mode can be greater than the symmetric mode, and the hybrid plasmonic WGMs have a greater mode index range, extending down to zero. Also, the mode indexes and Q factors of the resonance modes are measured by the attenuated total reflection and resonance linewidth method, respectively. The experimental results agree well with the theoretical.
