Abstract
We have observed optical emission from self-assembled InAs/GaAs quantum dots(QDs) embedded within the single-hole-defect, square-lattice (S1) photonic crystal microcavity. Cavities were measured to have quality factors as high as 4000. Finite-difference time-domain(FDTD) calculations were used to determine the specific S1 geometry that is resonant at the center of our ensemble QD spectrum. Extensive, systematic measurements fully confirmed the FDTD simulations and mapped resonant wavelengths as a function of varying lattice constant and hole radius of the photonic crystalstructures.Keywords
