Paper Abstract

We have measured optical attenuation in LiNbO3 and LiTaO3 waveguides due to exposure to an approximately 3 ns pulse of approximately 400 KeV electrons. The LiNbO3 operated at 810 nm and the LiTaO3 at 1309 nm. Both waveguides were formed using the annealed proton exchange method. Transient attenuation and recovery was observed for a series of pulse doses. To the accuracy of the measurements, total recovery was observed within 1 sec after exposure for both waveguides. Results from these waveguides were compared to earlier measurements of a titanium-indiffused LiNbO3 waveguide.
