Abstract :
We described design and fabrication of the light source, and demonstrated sevenfold photoluminescence (PL) enhancement from a single cavity. In this approach, photonic crystal cavities are used to enhance PL by increasing spontaneous emission rate from Si nanoparticles due to the Purcell effect, and by increasing collection efficiency. Here we report our results on the measured photoluminescence decay time, cavity design optimization, and efficiency of the material.
