GRASP is a three-year research project funded by the FP7 Cooperation FET-Open Xtrack Programme of the Directorate-General for Research of the European Commission.
In this project we will theoretically and experimentally pursue a fundamentally new paradigm based upon graphene to realize nonlinear optics at the single-photon level, which eliminates all of the current technological barriers.
We aim for the first demonstration of the deterministic generation of non-classical light using graphene as an extraordinary "bulk" nonlinear material, rather than through the conventional use of individual quantum emitters.

GRAPHENE-BASED SINGLE-PHOTON NONLINEAR OPTICAL DEVICES (GRASP)

Finding an approach to actuate nonlinear optical effects at ultra-low powers and on chip-scale devices is one of the outstanding challenges in optics. The ultimate limit is the quantum regime where individual light quanta strongly interact with each other, which would have far-reaching consequences in information technologies if achieved.

In particular, it would enable the best possible performance and wide deployment of classical nonlinear devices, and facilitate disruptive quantum information protocols that fundamentally cannot be realized on classical platforms. The primary obstacle is the weak nonlinear response of available optical materials, which necessitates high intensities and long interaction times to induce nonlinear effects.

In this project we will theoretically and experimentally pursue a fundamentally new paradigm - graphene-based single-photon nonlinear optics - that eliminates all of the current barriers. We aim for the first demonstration of the deterministic generation of non-classical light using graphene as an extraordinary "bulk" nonlinear material, rather than through the conventional use of individual quantum emitters.

 

Graphene-Based Single-Photon Nonlinear Optics (GRASP) is a three-year research project funded by the FP7 Cooperation FET-Open Xtrack Programme of the Directorate-General for Research of the European Commission. The project started on January 1, 2014 and has a collaboration consortium composed of four European partners. GRASP incorporates the expertise of the University of Exeter, Humboldt-Universitat Zu Berlin, Universitaet Wien and the Institute of Photonic Sciences, the institution that coordinates the project. The partners are internationally recognized in the fields of graphene, nano-photonics, quantum optics, and quantum information science, and have a strong history of launching innovative multi-disciplinary research directions.
