Optical Communications and Nanophotonics

The second focus of our electronic engineering research is in Optical communications and Nanophotonics for which Bangor has a long-established international reputation.

This research theme has received a major boost through the funding of the Digital Signal Processing Centre of Excellence, with major industrial partners including Huawei and BT, and based at the University’s M-Sparc Science Park.

Research Highlights
