High-dimensional entangled photon states.
DC FLEXMIL
Development and Control of Flexible Mode-locked Integrated Laser
Project Objectives
DC FlexMIL is an individual global fellowship research action focusing on the development and control of novel integrated classical and non-classical light sources for applications in e.g. metrology and quantum technologies. It merges fundamental scientific investigations with recent advances in integrated photonics and fiber-based telecommunications technology to reach its goals.
Project Funding
The project received funding from the European Union’s Horizon 2020 Research and Innovation programme under the Marie SklodowskaCurie grant agreement number 656607.
Project Partners
• INRS-EMT (Institut national de la recherche scientifique Centre – Energie Matériaux Télécommunications), Canada. • University of Glasgow, UK.

Miniaturised photonic system
Dr Michael Kues is conducting research on broad and interdisciplinary range of topics at the intersection of photonics and quantum science. In his current research, he focuses on the development and realization of compact on-chip optical quantum systems, and studies new and scalable optical approaches for present and future practical quantum information processing.

Researchers are not only looking into the generation of these quantum states in the project, but also how this can be achieved efficiently, through a small, practical and easily controllable system. Usually fairly large and complex systems are required, involving expensive optical free-space setups; Dr Kues and his colleagues in the project looked at an alternative approach. “Our approach is to miniaturise this and integrate it, making it easier to set up and use,” he says. The microring resonator is integrated on a chip, so it is more practical to use than previous systems. “We aim to slim it down, so that you can put these integrated light sources in a small box, instead of relying on large optical free space systems. This means it could not only be used in a special laboratory environment, but in out-of-lab scenarios,” continues Dr Kues. “We will continue working on this in future, to look into further miniaturising this, with the final goal of having the whole system integrated on a chip.” The project’s research could hold important implications for the future of quantum computing, as well as metrology,
telecommunications, spectroscopy and several other areas. The project itself recently concluded yet there is still scope for further research, and in future Dr Kues and his colleagues plan to explore the potential of these systems with respect to certain applications. “This could include sensing applications, for example,” he says. “The EU has established the Quantum Flagship to support continued investigation and help translate research into commercial development, which could propel this research further.” This type of research is very much collaborative in nature, and scientists from all over the world have made important contributions. As the recipient of this individual fellowship, Dr Kues has benefitted from the opportunity to spend time at INRS-EMT in Canada and University of Glasgow in UK, and the opportunity to share knowledge and ideas with international colleagues was central to the achievements of the project. “This research has been undertaken in a large collaboration, together with a core team at INRS-EMT, Canada and other places, who made important contributions to this work,” he stresses.
