Description
Optical communications have had a remarkable development over the last 50 years thanks to developments in, e.g., fiber optics, laser technology, optical amplifiers and signal processing. Fiber communications form the backbone of there internet, and one can now readily transmit 10-100 Tb/s over transoceanic distances. The presentation will briefly describe these developments, and then discuss the emerging challenges when we want to take optical communications into space, where distances can be even longer and where we will not benefit from fiber waveguiding, but the diffraction losses instead poses a significant challenge to the available data rates.
