Optoelectronic Data Link Designed for Applications in a Radiation Environment

We report here on component studies on a 10 m long, optoelectronic data transmission link designed for operation in a radiation environment. Our results show good immunity to neutron fluence levels of approximately 2 × 1014 n/cm2 and gamma radiation levels of 107 rad (Si). These results suggest that radiation hardened optoelectronic data links can be designed to operate in severe environments by carefully selecting components from the existing optoelectronics technology base.
