Photon Pair source

</a><strong>Background<br>

</strong>For high security quantum cryptography electrically triggered single or entangled photon sources are needed. In addition the mass market requires efficient, electrically driven, high-speed devices. A single or entangled photon source allows to use common growth and processing techniques for fabrication.</p> <p><!–break–></p> <p class=”MsoNormal” style=”margin-bottom: 0.0001pt;”><strong>Technology</strong><br> We offer a method for producing a photon pair source, 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.<br> </p> <p class=”MsoNormal” style=”margin-bottom: 0.0001pt;”> <strong>Benefits</strong><br> <ul> <li>Compact photon pair source</li> <li>High repetition rate</li> <li>Produces photons on-demand</li> <li>Simple and reproducible fabrication method</li> </ul><br> <strong>IP Rights</strong><br> German Patent DE 102008036400 B3<br> PCT application (EP, JP, CN, IN, KR)<br> <br> <strong>Patent Owner</strong><br> Technische Universität Berlin, Germany</p>
