Photonics Seminar: Andrea Ferrari, University of Cambridge

Please join the ASRC Photonics Initiative for a one-hour seminar, presented by Andrea Ferrari, University of Cambridge, titled:

Layered Materials: Characterization and Applications

Abstract – Graphene and layered materials (LMs) have great potential in photonics and optoelectronics, where the combination of their optical and electronic properties can be fully exploited, and the absence of a bandgap in graphene can be beneficial. The linear dispersion of the Dirac electrons in graphene enables ultra-wide-band tunability as well as gate controllable third-harmonic enhancement over an ultra-broad bandwidth, paving the way for electrically tuneable broadband frequency converters for optical communications and signal processing. Saturable absorption is observed as a consequence of Pauli blocking and can be exploited for mode-locking of a variety of ultrafast and broadband lasers. Graphene integrated photonics is a platform for wafer scale manufacturing of modulators, detectors and switches for next generation datacom and telecom. Heterostructures based on LMs have properties different from those of their individual constituents and of their three dimensional counterparts. These can be exploited in novel light emitting devices, such as single photon emitters, and tuneable light emitting diodes. LMs have potential for quantum technologies, as scalable sources of single photon emitters (SPEs). Quantum emitters in LMs hold potential in terms of scalability, miniaturization, integration. Generation of quantum emission from the recombination of indirect excitons in heterostructures made of different LMs is a path with enormous potential. I will overview production, characterization and application of graphene and LMs, focussing optical and quantum applications.
