Two-photon absorption coefficients in a standard telecommunication fiber are measured in the range of 440-560 nm with a tunable pulsed dye laser as a light source. The measured two-photon absorption coefficients showed a maximum at 480 nm. This wavelength is twice those of oxygen-deficiency defects. The maximum value was 1.3 10 -4 cm/MW. From the magnitude of this value, it is...
Photosensitivity in germanosilicate optical fibers is studied with a fiber Michelson interferometer. Saturation characteristics for multiple KrF-laser exposure are measured, and the origin of the index change is discussed. The total index change of a high-Ge (35 mol%) fiber is 6 times that of a low-Ge (3 mol%) fiber. In both fibers, the fast and the slow saturation components are found. An analysis...
