High quality semiconductor microcavities have attracted considerable attention as a compact solid state platform for the investigation of light-matter interaction between photons and excitons in single quantum dots. Owing to a combined optimization of the design (increased number of mirror pairs), the growth conditions (V/III ratio) and the dry etching process we were able to achieve record quality...
We report on strong coupling between a discrete optical mode of a high-Q micropillar cavity and single excitons of self assembled In0.43Ga0.57As quantum dots and compare the results with previous studies on In0.3Ga0.7As quantum dots.
A high-Q vertical emitting AlAs/GaAs Fabry-Perot micropillar cavities are fabricated, with a new type of GaInAs quantum dots within a one lambda-cavity using high reflectivity distributed Bragg reflectors. In this paper, micropillars with a maximum quality factor of up to 34500 for a 4 mum wide microcavity are presented
