    "abstract": "Scattering processes in an optical microcavity are investigated for the case\nof silicon nanocrystals embedded in an ultra-high Q toroid microcavity. Using a\nnovel measurement technique based on the observable mode-splitting, we\ndemonstrate that light scattering is highly preferential: more than 99.8% of\nthe scattered photon flux is scattered into the original doubly-degenerate\ncavity modes. The large capture efficiency is attributed to an increased\nscattering rate into the cavity mode, due to the enhancement of the optical\ndensity of states over the free space value and has the same origin as the\nPurcell effect in spontaneous emission. The experimentally determined Purcell\nfactor amounts to 883.",
