Abstract

The optical absorption spectrum and the 400-nm photoluminescence (PL) of a 1.4-mol. % Ge photosensitive optical fiber preform subjected to high fluence of 193-nm ArF and 248-nm KrF excimer-laser irradiation are measured. The largest absorption increases occur near 200  nm in both cases, but a small net bleaching of absorption is obtained near the laser wavelength for KrF irradiations. The blue PL decreases during ArF exposure but increases with the KrF laser. In similarly excited 9-mol. % Ge fiber preforms the blue PL always decreases. A study of the PL intensity as a function of irradiating laser light intensity shows no evidence of multiple photon absorption effects.
