Tuning the single optical mode spontaneous emission coupling of a quantum dot in a micropost cavity
Using a micropost cavity, the emission from a quantum dot (QD) is coupled to the discrete fundamental optical mode of the cavity. By adjusting the temperature of the device between 4 and 70 K, the coupling between the QD and the cavity can be tuned. The ratio of the spontaneous emission decay rate between on and off resonance is approximately 4. (C) 2003 Published by Elsevier Science B.V.
