ABSTRACT
We report the coupling of individual InAs quantum dots (QDs) to an external-mirror microcavity. The external mirror is bonded to a fiber and positioned above a semiconductor sample consisting of a QD-containing GaAs layer on top of a distributed Bragg reflector. This open cavity can be rapidly tuned with a piezo-electric actuator without negatively affecting the QD linewidth. A mirror radius of curvature of 42 μm and a cavity length of 10 μm enable good mode matching and thus high collection efficiency directly into the fiber. With an improved finesse, this system may enter the strong coupling regime.

    A novel concept for creating self-doping quantum wires and quantum dot arrays based upon the InAs-GaSb material system is proposed. The unusual type II, broken-gap band line-up in this system allows charge transfer across the InAs-GaSb interfaces. We employ a recently developed coupled band...

    A combined InAlAs and GaAs strained buffer layer was presented to tailor the structural and optical properties of 1.3-µm InAs/GaAs quantum dots. This growth technique exhibits an increment of InAs quantum-dot density from 1.6 × 10[sup 10] to 2.8 × 10[sup 10] cm[sup -2] and an...
