Fiber taper waveguides are used to improve the efficiency of room temperaturephotoluminescence measurements of AlGaAs microdisk resonant cavities withembedded self-assembled InAs quantum dots. As a near-field collection optic,the fiber taper improves the collection efficiency from microdisk lasers by afactor of ~ 15-100 times in comparison to conventional normal incidencefree-space collection techniques. In addition, the fiber taper can serve as aefficient means for pumping these devices, and initial measurements employingfiber pumping and collection are presented. Implications of this work towardschip-based cavity quantum electrodynamics experiments are discussed.Comment: 10 pages, 7 figure
