Radiation tolerant optoelectronics for high energy physics

Optical data transfer has become ubiquitous in the readout and control systems of High Energy Physics Experiments. We review the motivations for this and describe the first large-scale deployments of optical links in the LHC experiments. The current state of the art in the form of the common developments for the LHC upgrade programmes is then summarised. Finally, new technologies and techniques are reviewed and confronted with the needs across the broad spectrum of potential future applications in High Energy Physics.
