Abstract: the enormous growth of datacom and telecom technologies over the last few decades requires constant improvement in terms of bandwidth, consumption, and cost, posing great technological challenges. At front of ever-increasing requests (as foreseen in the Ethernet roadmap), existing technology encounters limitations in terms of footprint, power consumption, and cost of integration. Graphene-based photonic devices have the potential to solve many of these issues; however, the extent of graphene adoption will depend on the possibility to maintain its high intrinsic quality when processing it using the industry-standard approaches. In this talk the challenges of scalable graphene integration [1-3], the recent demonstration of photonic building blocks [4-6], and the opportunities presented by such technological advances will be discussed.

Short Biography: Camilla Coletti is a tenured Senior Scientist of the Istituto Italiano di Tecnologia (IIT) and principal investigator of the research line 2D Materials Engineering: She is the coordinator of the Center for Nanotechnology Innovation (CNI@NEST) of Pisa and of the Graphene Labs. She has been hired by IIT in 2011 after being an Alexander von Humboldt postdoctoral fellow at the Max Planck Institute for Solid State Research of Stuttgart (Germany). She received her PhD degree from the University of South Florida in 2007 and her MS degree from the University of Perugia in 2004 (with honors, both in Electrical Engineering). She is expert in the synthesis of highly-crystalline 2D materials via chemical vapour deposition (CVD) and in the investigation of their electronic, chemical and structural properties. Her research is focused on: (i) synthesis and integration of scalable 2D materials for optoelectronics, photonics and biomedicine; (ii) engineering the interface and properties of 2D heterostructures. In her work she applies her background of surface scientist to impact science and technology of 2D materials. Over the years, within IIT, she has directly supervised over 40 students and postdocs, with a great attention in creating an international and gender fair environment. She has received funding for about 4 M€ from competitive grants and industrial contracts. In the last years she has been an invited speaker at prestigious conferences in the field (e.g., Graphene Week, Graphene 20xx, MRS Spring/Fall), she organized symposia and workshops (e.g., Japan-EU Flagship Workshops, MRS Symposia), and she was a lecturer at Summer/Winter Schools (e.g., Graphene Winter School, Nano-Network, Cambridge Advanced Technology Lectures). Since 2020 she is Faculty Board Member for the PhD in Nanoscience at the Scuola Normale Superiore (SNS) of Pisa and throughout the years she has been a lecturer for courses at the Master’s and PhD level (University of Pisa, University of Genova, SNS). Overall, she is author of more than 120 peer-reviewed publications, authored 4 book chapters, edited 1 book, filed several international patents (holds 3) and delivered more than 50 invited talks at international conferences.
