Seminar: "Glasses for Photonics and Specialty Optical Fibres Group at the Politecnico di Torino" by Professor Monica Ferraris
Friday, January 22, 2016 10:00 AM to 11:00 AM
CREOL Room 102/103
Professor Monica Ferraris
Politecnico di Torino
ABSTRACT:
The activity on new glasses for photonics and sensing done at Politecnico di Torino during the past 20 years will be briefly reviewed and discussed. In particular, examples will be given on soft glass optical fibers for several applications, ranging from optical fiber lasers and amplifiers to supercontinuum generation and remote sensing/switching applications. Examples of passive and active tellurite glasses and optical fibers for telecom, sensing and Red-Green-Blue sources and rare earth doped phosphate glasses and optical fibersfor short pulsed fiber lasers will be presented. Soft glasses are prepared by melt quenching technique in a controlled atmosphere furnace and then cast on brass molds. The preforms are fabricated by rod-in-tube technique with the tubes manufactured using the rotational casting technique. Specialty optical fibers are fabricated by preform drawing carried out using an in-house custom optical fiber drawing tower. In-line measurement of fiber diameter and tension has enabled stable and reproducible optical fibers suitable for the demonstration of amplification and laser activity.
Some cross-cutting activities have been recently started dealing with the design and fabrication of bioresorbable optical fibres for diagnosis and therapy and with RF co-sputtering of metal nanocluster doped silica thin films for antiseptic and/or bio-sensing application. Preliminary results will be reported.
BIOGRAPHY:
Prof. Monica Ferraris received a M.S. in Chemistry in 1985 from the University of Torino, Italy. In 1985 she joined the Italian Telecom Research Centre (CSELT-Torino) to work on fluoride glasses for ultra low loss optical fibers. In 1990 she moved to Fiat Research Centre (CRF-Torino) where she worked on metal and ceramic matrix composites for automotive applications. She joined Politecnico di Torino in 1991, where she is now full Professor of Materials Science and Technology (since 2005) and group leader (
