“…Several studies [32][33][34][35][36][37][38][39][40] have shown that radiation-induced displacement damage in the semiconductor lattice 01' the active, light-producing region in LEDs and ILDs is the most serious effect of a typical mixed radiation environment. The key to understanding the detrimental effects of lattice damage on the performance of LEDs lies in an examination of the operating mechanisms of these devices.…”

Ken .label @ g sfc.nasa.gov (301) 286-9936Abstruct-As civilian and military spacecraft continue to evolve, meeting performance demands will become particularly challenging because performance levels will be constrained by severe cost and weight restrictions. To meet these challenges, new technologies, such as photonics, w i l l be employed that can provide desired performance levels within the framework dictated by these constraints. For the insertion of a new technology into a spacecraft to be successful, the radiation hardness assurance (RHA) of the technology must be established so that the mission is not jeopardized by exposure to the space radiation environment. In this paper we discuss the RHA issues associated with the infusion of photonics into space systems, both military and civilian. These issues w i l l be contrasted with similar problems that have been encountered in the more traditional area of RHA for Si microcircuits.

“…This last value is compatible with that from [61: about 300 dB/km obtained with a much higher dose-rate of 7200 kGy h1. The gamma-ray tolerance in 820-900 nm-wavelength fiber optic systems is mainly determined by light output degradation of Al Ga As LEDs [8,9]. Presently not many results were published for 1.3 j.m-LEDs.…”

With the increasing use of optical data links it becomes essential to test for radiation vulnerability not only the transmission support -fiber and cable -but also fiber-end electro-optical components that could be exposed to hostile environment. Numerous silica-based fibers were currently tested over the world. Present paper gives a comparison of radiation resistance between two gradient index multimode fibers with and without phosphor in core. From that result a technological change in standard 1.3 m wavelength light-emitting diodes (LED), injection-laser diodes (LD) and p-i-n photodiodes (PD) was made. Results of tests under steady-state medium dose-rate Co° exposure show a significant enhancement of improved components optical performance. Especially LED and PD present a small degradation of optical caracteristics for 50 kGy (for a dose-rate of about a few 10 Gy h1). Multicomponent laser-diode modules (LDM) were extensively tested up to about 20 kGy. Two degradation processes clearly appear : a wrong decrease of stimulated light emission after 3-4 kGy and a bad operation of thermoelectric element cooler beyond about 10 kGy. Hardened optical data links are now able to withstand successfully some nuclear environments.
