Abstract

The authors report on AlAs/ GaAs micropillar cavities with unprecedented quality factors based on high reflectivity distributed Bragg reflectors (DBRs). Due to an increased number of mirror pairs in the DBRs and an optimized etching process record quality (Q) factors up to 165.000 are observed for micropillars with diameters of 4 mu m. Optical studies reveal a very small ellipticity of 5 X 10(-4) of the pillar cross section. Because of the high Q factors, strong coupling with a vacuum Rabi splitting of 23 mu eV is observed for micropillars with a diameter of 3 mu m. (c) 2007 American Institute of Physics.
