LiTaO3 and LiNbO3:Ti responses to ionizing radiation

Optical guided wave devices can experience crosstalk and mode-switching in the presence of ionizing radiation. This paper discusses the response of LiTaO 3 and LiNbO 3 :Ti directional coupler waveguides to exposures of linearly accelerated electrons. A comparison of the waveguides in terms of sensitivity to the ionizing radiation is made.
