Abstract

We have measured the two-photon absorption coefficent at 0.527 mu m to be 1.8 +/- 0.4 x 10(-3) cm/GW in a germanium-doped silica fiber. Using absorption and luminescence measurements we estimated the two-photon absorption coefficient at 1.053 mu m to be smaller than 6 X 10(-7) cm/GW. Using a capacitive technique we measured the photoconductivity to be approximately 6 X 10(-9) 1/Ohm cm in the visible. The photoconductivity inreased linearly with intensity. A qualitative discussion of the defect dynamics related to photosensitive phenomena in optical glass fibers is given based on the experimental results. (C) 1996 AmericanInstitute of Physics.
