Satellite-based links are of key importance to provide ever-increasing data rates. Free-space optics is a technology that can help satisfy this demand thanks to the vast amounts of bandwidth available in the THz-regime. The Eindhoven University of Technology recognizes the crucial paradigm shift, from intensity-modulated to coherent transmission, necessary in next generation FSO communication systems to provide high throughputs. To address this challenge, we are excited to announce 2 EngD positions (P1 & P2) in the field of experimental FSO communications.
