Wafer-scale integration of graphene and TMDs for photonics

Wafer-scale integration of graphene and TMDs for photonics (Coletti):

ultra-high mobility graphene matrixes will be processed over wafer scale (300 mm) to obtain performing photonic components for next generation Datacom and Telecom communications. Interface engineering with photonic platforms and oxides, contacts and device design will be optimized to obtain photodetectors and modulators operating at record data rate while saving on energy consumption and footprint. 2D TMDs will be integrated on 300 mm wafers as active and/or passive layers to improve the performance of photonic building blocks. Collaboration with WP3, WP15 and WP16.

Graphene-enabled coherent Raman

Graphene-enabled coherent Raman microscope for tumor diagnostics (Scopigno):

develop a prototype of Coherent Raman Scattering (CRS) microscope up to the stage of demonstration in a relevant healthcare environment, for application in tumor diagnostics. CRS is a label-free and non-invasive biomedical imaging technique, which makes it possible to obtain objective and quantitative information on the tissue, by measuring its detailed molecular composition, and has a proven capability to discriminate between healthy and tumor tissue and to identify the type and grade of tumor. By introducing an ultrafast graphene-enabled laser the main hurdle preventing the adoption of this technique (i.e., the complication and cost of the required laser system) will be solved. The laser concept is simplified with respect to existing commercial solutions. It is turn-key, thanks to the fiber architecture and can be manufactured at a fraction of the cost, thus removing the main technical hurdle towards the commercialization of CRS microscopy, fostering its broad adoption in biomedicine as well as in materials science. Collaboration with WP4, WP5 and WP16.
