Abstract

We report the coupling of individual InAs quantum dots (QDs) to a single mode of an external-mirror optical microcavity. The external mirror is bonded to a fiber and positioned above a semiconductor sample consisting of a QD-containing GaAs layer grown over a distributed Bragg reflector (DBR). Unlike fully-integrated temperature-tuned microcavities, this open cavity can be rapidly and precisely tuned without changing the QD frequency nor deteriorating its linewidth. With a mirror radius of curvature of 42 microns and a cavity length of 10 microns, the spot size at the concave mirror is closely matched to the single-mode fi ber, off ering high collection effciency directly into the fi ber. With an improved fi nesse (currently F=1000), this system may enter the strong coupling regime.
