Manufacturer's Description

We endeavor to develop single photon emitters based on group III nitride nano-LEDs (light emitting diodes). Due to their room temperature operation, they may enable highly secure and fast quantum cryptography based on single photon emitters. The key challenge in this technology is to develop single photon emitter, which emit on demand a single photon with very high repetition rates, which has not been achieved for electrically pumped single photon sources. To this end we investigate a hybrid approach to explore plasmonic effects leading to a field enhancement at the position of a light emitting nanoparticle serving as the single photon source. The colloidal II/VI nanoparticles are electro-optically pumped as the secondary excitation sources by electrically driven nano-LEDs as the primary excitation sources. The hybrid system is well suited to tune the emission wavelength in dependence of the size of the colloidal nanoparticle. The nanoparticle is embedded in an Au nanostructure, designed to tailor efficient absorption and stimulate photon emission.
