Abstract
A report is presented of a subminiature solid-state emitter structure, which allows electrical pumping of only one single InAs quantum dot (QD) grown in the Stranski-Krastanow mode. The emitter demonstrates a strongly monochromatic polarised emission of a single QD exciton. No other emission is observed across 500 nm. The structure is thus attractive for practical implementation as an effective single photon source for quantum cryptography.
