GaAs-based semiconductor microdisks with high quality whispering gallery modes (Q 4 4000) have been fabricated. A layer of self-organized InAs quantum dots (QDs) served as a light source to feed the optical modes at room temperature. In order to achieve frequency tuning of the optical modes, the mic
