Photonics Seminar Series 2011/2012 - "Interfacing quantum dots to atomic vapors"

Interfacing quantum dots to atomic vapors

Main Conference Room

Abstract:

Artifical and natural atoms offer complementary properties where quantum dots are scalable sources of non-classical light while atomic vapoours offer long coherence times and frequency standards. Using specially designed GaAs/AlGaAs quantum dots, we demonstrate coupling of the emission from a single quantum dot to a rubidium vapour, enabling the combination of solid state and atomic systems. Our hybrid artificial-natural atoms systems enable experiments such as slow light at the single photon level, frequency locking of a single quantum dot to counteract spectral wandering, to make a set of quantum dot indistinguishable in their emission and quantum memories where light generated by a quantum dot could be stored in an atomic vapor.
