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.
