Physics and Applications enabled by integrated silicon photonic circuits

Here I will review few topics we are currently working on in the Nanoscience Laboratory of the University of Trento (http://nanolab.physics.unitn.it/). Specifically by using the silicon photonics platform we are working on non-hermitian photonics in taiji microresonators [1], on microresonator based time-delayed neural networks [2,3], on heralded single photon sources for MIR ghost spectroscopy [4] and on the use of single particle entanglement to produce self-testing quantum random number generators [5].

Speaker's Bio

Lorenzo Pavesi is Professor of Experimental Physics at the Department of Physics of the University of Trento (Italy). He leads the Nanoscience Laboratory and director of the Quantum at Trento joint laboratory. He has directed 37 PhD students and more than 30 Master thesis students. His research activity concerned the optical properties of semiconductors. 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. Recent development is toward integrated quantum photonics and neuromorphic photonics. He is an ERC grantee. He is a frequently invited reviewer, monitor or referee for photonics projects by several grant agencies. 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 9 patents. He is chief speciality editor of the section Optics and Photonics of Frontiers in Physics and founding editor of the series Photonic Materials and Applications, a joint initiative of SPIE and Elsevier. 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 fellow of the IEEE, of SPIE, of AAIA and of the SIF.
