08044/TUB: Photon Pair Source
Electrically triggered single or entangled photon sources are needed for high security quantum cryptography. In addition, the mass market requires efficient electrically driven high-speed devices. A single or entangled photon source allows the use of common growth and processing techniques for fabrication.
We offer a method for producing a photon pair source in a simple and reproducible manner, which generates entangled photon pairs. This method offers a minimization of the fine structure splitting in quantum dots (QDs) to nearly zero using (1,1,1)-orientated semiconductor substrates.
The invention allows producing a single photon source which can be used for quantum cryptography.
