Classical Purcell factors and spontaneous emission decay rates in a linear gain medium
Juanjuan Ren, Sebastian Franke, Becca VanDrunen, Stephen Hughes
Abstract
The authors derive a correction to the spontaneous emission rate and the classical Purcell factor in linear media that includes gain and loss within the framework of a classical light-matter theory. The results fully recover a recently presented quantum mechanical form, establishing an essential classical-to-quantum correspondence of spontaneous emission, and are extended to also account for local field effects.
