Abstract

The properties of porous silicon microcavities impregnated with a laser dye are investigated by photoluminescence and reflection measurements. The spontaneous emission spectrum of the optically excited rhodamine 800 is drastically modified by microcavity effects: the peak emission intensity is increased, the linewidth is narrowed. These results demonstrate that using all porous silicon or dye-filled microcavities provides new possibilities to improve the properties of photonic devices.
