The enhanced radiative rate of an emitter within a microcavity relative to its value in free-space. For maximal coupling (on-resonance and with the emitter positioned at a field maximum):
where (λc / n) is the wavelength within the material, and Q and V are the Quality Factor and mode volume (in cubic-wavelengths) of the cavity, respectively.
