The efficient generation of quantum states of light is a vital task in Quantum Photonics. Current approaches are bulky and expensive with low generation rates and there is only a handful of commercial products. CUSPIDOR will develop a novel integrated photonic platform relying on a fully CMOS-compatible technology, which will provide compact and highly efficient sources of deterministic single photons at telecommunications wavelengths. Using quantum electro-dynamics principles, silicon-germanium quantum dots (QDs) in silicon will be optimized for radiative efficiency up to room temperature. Ion implantation will be implemented during the growth, thus modifying the electron wave function and improving the radiative recombination rate. Optimal and deterministic coupling of the QDs with the cavities will be achieved by site controlled QD growth in combination with precisely aligned, lithographically defined photonic crystal resonators, allowing upscaling and a straight forward implementation of areas of identical single photon sources.
The project will create a strong team of quantum photonics researchers proficient with material design and growth, advanced CMOS processes and nanophotonics design, who will become the basis of a new community spanning these diverse fields. A firm basis of design skills and fabrication expertise will be established that will provide a base for further innovation and the exploitation of quantum light sources.
This consortium will exploit the state-of-art advances in CMOS processing to realise advanced photonic crystal components that will dramatically improve the functionality of the silicon-germanium devices. The final target is a demonstrator for a compact, integrated, and flexible source of quantum states of light ready for prototyping.
