The Photonics Communications Research Laboratory (PCRL) was founded in September 1995 by Prof. Hercules Avramopoulos, as a research facility of the School of Electrical and Computer Engineering of National Technical University of Athens (NTUA), and member of the Institute of Communications & Computer Systems (ICCS). It currently numbers 20 doctoral and post-doctoral researchers whose research interests include optical interconnects and telecommunications, digital signal processing, photonic integrated circuit (PIC) design, and biophotonics/sensing. PCRL runs a fully equipped laboratory with state-of-the-art test and measurement systems and a broad range of passive and active photonic devices. PCRL is actively involved in collaborative research projects at a national and European level and has participated in over 25 projects over the past 10 years, acting as the project coordinator for many of them. Throughout its track record in photonics research, PCRL has established worldwide links and collaborations with top research institutes and industrial research organizations.
