Obtained his Licenciado in Physics from Universidad de Buenos Aires (1976) and his Ph.D. in Physics from Universidade Estadual de Campinas (Unicamp, 1984). He was visiting researcher at AT&T Bell Labs (Holmdel, NJ, 1987-1989). Presently he is Full Professor at Presbyterian University Mackenzie and collaborator at University of Campinas (Unicamp), and member of Physics committee at Fapesp. He served as Director of the Optics and Photonics Research Center at Unicamp (CEPID CePOF-Unicamp), Coordinator of the National Institute of Photonics Science and Technology for Optical Communications (INCT Fotonicom), Coordinator of the KyaTera Project, and member of the program committee of Fapesp's Infomation Technologies for the Advance of the Internet (TIDIA). He is member of the OSA Optical Society of America, the IEEE Photonics Society, and the Brazilian Physics Society. Prof. Fragnito works in the fields of nonlinear optics in fibers and waveguides, parametric devices, Graphene-based ultracompact modulators, optical properties and ultrafast relaxation mechanisms in 2D materials.

Endowed with unique electronic and structural properties, 2D materials exhibit extraordinarily strong nonlinear and ultrafast responses to light. The variety of their electronic structures ranging from the gapless Dirac cone of graphene to variable band-gap materials such as Phosphorene and Transition Metal Di-Chalcogenides (TMDC) to the insulator Boron Nitride (BN) provides a broad spec…
This project is currently being submitted within the Thematic Projects line following the advice of FAPESP's Area Coordination, and consists of the same project previously submitted and well refereed in the Young Researchers line [process no. 2012/18400-2]. There has been no change in the budget and only minor amendments in the text were made in this cover page and in section 6 (marked in…
This project aims to explore the excellent optical properties of graphene, both from the standpoint of basic research as the study of nonlinear optical response, and from the applied perspective, with the development of optoelectronic and photonic devices. For this purpose, the MackGrafe research center at Mackenzie Presbyterian University (UPM) is being built, with facilities for growth,…

The main goal of this research is to understand what makes a 2D structured material more nonlinear and faster than others, and how to explore these understanding to design and demonstrate efficient photonic devices that might be used in signal processing or sensing. The post-doctorate fellow will be involved in sample fabrication and characterization of the 2D materials, and the design an…
The selected student will study experimentally and theoretically the nonlinear optical properties of pure and functionalized graphene, participating in scientific collaborations with other groups in this project, including groups abroad. The nonlinearities to study are saturable absorption and wave mixing, the student will use the techniques of pump & probe and laser induced gratings, aim…
Silicon photonics has emerged as a promising platform for optical communication devices and optical signal processing applications. Itscompatibility with CMOS (Complimentary Metal Oxide Semiconductor)fabrication process allows the implementation of micro-structured siliconwaveguides, making it potentially cost-efficient for future optical integratedsystems. One challenge associated with S…
