Fiber-coupled, high-quality-factor (Q > 10^5) AlGaAs microdisks with embedded InAs quantum dots are demonstrated. Microdisk lasers employing evanescent fiber coupling for optical pumping and collection of emission exhibit up to two orders of magnitude improvement in differential efficiency compared to devices probed through normal-incidence, free-space photoluminescence. The fiber taper coupling is also shown to provide an efficient optical channel for studying and manipulating the microcavity-quantum dot system, with in-fiber cavity mode collection efficiences greater than 20% and cavity loading approaching critical coupling. Progress and current challenges in incorporating such fiber-coupled devices into low temperature experiments for studying coherent interaction between single quantum dot and single cavity mode excitations will be discussed.
