Abstract :
We show that conventional expressions for spontaneous emission into waveguide modes correctly predict broadband (non-resonant) Purcell enhancement in slot waveguides. Time resolved photoluminescence measurements on Er-doped ultra-thin 8.3 nm slot channel waveguides corroborate this effect.
