We report on visible light WGM emission and time-resolved studies of Purcell enhancement from Si-nanocrystal-based all-active microdisk resonators. The observed significant, 13-fold mode narrowing (Q~2800) at lowest excitation powers is attributed to the attenuation of pump-induced excited carrier absorption loss mechanism.

Abstract
We report on visible light WGM emission and time-resolved studies of Purcell enhancement from Si-nanocrystal-based all-active microdisk resonators. The observed significant, 13-fold mode narrowing (Q~2800) at lowest excitation powers is attributed to the attenuation of pump-induced excited carrier absorption loss mechanism.File in questo prodotto:
