报告题目：Classical and Quantum Integrated Silicon Photonics
Professor of Experimental Physics at the Department of Physics of the University of Trento (Italy). He received his PhD in Physics in 1990 at the Ecole Polytechnique Federale of Lausanne (Switzerland). In 1990 he became Assistant Professor, an Associate Professor in 1999 and Full Professor in 2002 at the University of Trento. He leads the Nanoscience Laboratory (25 people), teaches several classes at the Department of Physics of the University of Trento. He founded the research activity in semiconductor optoelectronics at the University of Trento and started several laboratories of photonics, growth and advanced treatment of materials. He was the first president and founder of the IEEE italian chapter on Nanotechnology. He was the head of the Department of Physics (2012-2018). During the last years, he concentrated on Silicon based photonics where he looks for the convergence between photonics and electronics. He is interested in active photonics devices which can be integrated in silicon by using optical nolinearities and modified material properties. His interests encompass also optical sensors or biosensors and solar cells. Recent development is toward integrated quantum photonics. In silicon photonics, he is one of the worldwide recognized experts, he organized several international conferences, workshops and schools and is a frequently invited speaker. He manages several research projects, both national and international. He is an author or co-author of more than 500 papers, author of several reviews, editor of more than 15 books, author of 2 books and holds 7 patents. He is chief speciality editor of the section Optics and Photonics of Frontiers in Materials and in the Editorial Advisory Board of APL Materials. Moreover he sits in the editorial board of the ETRI Journal and of the journal Applied Sciences: Optics and Lasers. He is in the advisory board of Glass-to-Power and of Sybilla, two italian start-up. In 2001 he was awarded the title of Cavaliere by the Italian President for scientific merit. In 2010 and 2011 he was elected distinguished speaker of the IEEE- Photonics society. He is a fellow of the IEEE and of the SIF. He is senior member of SPIE. He holds an H-number of 57 according to the web of science or Scopus and of 67 according to Google Scholar.
This talk reviews the use of Silicon Photonics as a platform to integrate classical as well as quantum photonics. Silicon Photonics is the technology to fabricate photonics devices with standard silicon microelectronics processing. Few examples will be demonstrated: a heavily integrated transponder aggregator based on optical switches for application in telecom networks and data centers, a compact biosensor for screening toxins which is fully functional and allows on field testing of milk, a chip size quantum random number generator for secure quantum communication, and an integrated source of heralded single photons for the MIR.
