Nonclassical Light from Single Semiconductor Quantum Dots

Abstract

In this article the recent progress in the generation of nonclassical light using semiconductor quantum dots is reviewed. Photon antibunching and triggered single photon emission for both optical and electrical pumping has been observed. The coupling of a single self-assembled quantum dot to a high-quality factor cavity mode is obtained. This gives access to the study of cavity-quantum electrodynamics (QED) effects, e.g., the Purcell effect in an all-semiconductor nanostructure. The positive impact of the Purcell effect on single photon emission is presented. Triggered correlated pairs of photons and the prospects for the generation of entangled photons will also be discussed.
