Abstract

The effect of neutron radiation on light emitters and optical fibers 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 fibers have been exposed to neutron radiation reaching fluences of 10¹⁵ neutrons/cm²
