Dr Cosimo Lacava

Research Staff

Cosimo graduated with honors in Electronic Engineering at the University of Pavia in 2011. He then joined the Quantum Electronics research group at the University of Pavia as \ PhD student, working on nonlinear optical properties of compact, integrated waveguides, mainly made by using the silicon photonics platform. He obtained his PhD in Optoelectronics and Electronic Engineering in 2014.

He continued working at the Quantum Electronics Laboratory as a Postdoc researcher, working on the development of novel silicon photonics transceiver devices for the next-generation optical network, in the frame of the “Fabulous” European Project. At the end of 2014 he moved to Southampton to join the ORC. His research interests are nonlinear optics , all optical signal processing, silicon photonic devices and integrated optics.
