Dr Cosimo Lacava

Research Staff

Cosimo graduated with honours 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 Postdoc researcher, working on the development of novel Silicon Photonics transceiver device 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 ORC as Research Fellow.
