Paper Abstract

The incremental loss induced at 1.3 μm in multimode and single mode optical fiber waveguides has been studied at 23 C and -55 C in situ as a function of time after high dose rate (9000 rads/min) steady state exposure and as a function of dose during low dose rate (- 1 rad/day) irradiation. Undoped and binary Ge-doped silica core fibers have demonstrated the lower radiation responses and better recoveries at 23 C; the induced losses substantially increase by factors of 8-18 when exposed at -55 C. Selective P doping on the fiber centerline or in the cladding has been found to reduce this temperature dependence, but increased damage and less recovery at 23 C have been noted. Measurements of the radiation response of Selfoc Microlenses have shown that the induced loss in a single lens at 1.3 I'm is only - 1 dB after an exposure of 2 x 104 rads; the SLS lenses are more radiation sensitive than the SLW lenses.
