The Photonic Networks and Technology Laboratory aims at the development of all the critical technology for delivering advanced fiber optic components, tunable devices for high-capacity optical networks and fiber sensors. The Photonic technology laboratory is a well-equipped laboratory. Its infrastructure includes 40 Gb/s electrical and lightwave test & measurement equipment, a state-of-the art C-band DWDM test-bed and a 10Gb/s, programmable GMPLS testbed. We are also working on fiber sensors and tunable devices either biomedical or telecom applications. PNET lab is part of Research Unit 1 of Computer Technology Institute (http://ru1.cti.gr/)
