Hamiltonian analysis of metal cavity light sources: nonradiative decay due to the metal cavity (Conference Presentation)
Author(s): Dennis G. Deppe

Paper Abstract

Metal cavities in some ways behave like non-metal cavities in creating optical modes confined by the cavity mirrors. However metal cavities create an additional physical effect when an emitter is placed in the cavity that is not included in the interaction between the cavity modes and the emitter. Not included in the Hamiltonian for the emitter-mode coupling is the nonradiative decay caused by the metal cavity walls acting on the longitudinal electromagnetic fields of the emitter. To capture the additional interaction includes an additional term in the Hamiltonian not usually captured, for example, by the metal cavity's modal analysis. This talk will address these Hamiltonians and present the analysis based on Green's functions solutions to the different Hamiltonians to address the added interactions. It is shown that a typical Maxwell' solver approach to find "empty" cavity modes is not adequate to predict how the cavity and emitter will work. Instead a complete Green's function solution that includes the longitudinal fields of the Hamiltonian must be used, which includes requiring the emitter's existence in the cavity. This added effect is shown to dramatically change predictions of efficiency and device operation for both lasers and spontaneous emitters that propose to use metal cavities.
