N2 - We develop a rigorous theory of the enhancement of spontaneous emission from a light-emitting device via coupling the radiant energy in and out of surface plasmon polaritons (SPPs) on the metaldielectric interface. We show that while the efficiency of coupling into the SPP mode can be quite high, the radiative efficiency of the SPP itself is relatively low, with a substantial fraction of the energy lost in the metal. Using the GaN/Ag system as an example we obtain easy-to-interpret analytical results that unequivocally indicate that using SPP pays off only for emitters that have medium-to-low luminescence efficiency.
