Abstract :
The effect of neutron radiation on light emitters and optical fibres at cryogenic temperatures (-184°C) has been investigated as part of the development of an analogue optical link, intended for use at future high energy physics experiments. The LED´s were also exposed to a gamma radiation dose of 3 MRad. High radiance GaAs LED´s, quantum-well LED´s, quantum-well laser diodes and optical fibres have been exposed to neutron radiation reaching fluences of 1015 neutrons/cm2
