Nanowires for quantum optics

We present optical measurements on nanowire heterostructured quantum dot devices. Quantum dots defined with hetero-material structures are presented as well as a novel type of quantum dot defined by the crystal phase of the semiconductor. We demonstrate the possibility of electrically addressing a single quantum dot with photocurrent and perform electroluminescence measurements on a single nanowire light emitting diode. The applicability of our devices to advanced quantum optics and quantum plasmonics measurements is discussed.
