Abstract

We consider the formation of the surface plasmon polariton whispering gallery modes in the convex cylinder cavity. Developed theoretical model allows obtaining the closed-form expressions for the mode field distributions, resonant frequency, as well as the emitting and dissipative losses in the structure in a broad wavelength range. The obtained results give opportunity to find optimal conditions for efficient emission in convex cylinder cavity and serve as practical guidelines for stimulated emission.
