Abstract
Three-dimensional photonic crystals used in this study were synthetic opals, composed of submicron silica spheres, close-packed in a face-centered cubic lattice with a period of 200 nm, which exhibit a photonic gap around 600 nm. We report on the first observation of optical gain enhancement in semiconductor quantum dots embedded in a photonic crystal caused by modifications of light-matter interaction at the edges of the photonic gap.
