Abstract

Summary form only given. We have fabricated waveguide based 2D photonic crystal defect microcavities. At moderate excitation powers below saturation it is possible to observe simultaneously both individual quantum dot emission tines and the cavity modes. Using the different temperature shifts of the quantum dot emission lines and the cavity modes, individual dots can be tuned in and out of resonance with the cavity. Thereby it is possible to control the spontaneous emission rate of individual quantum dots.
