Abstract
A theoretical modeling of continuous wave UV laser induced waveguides
in congruent LiNbO
$_{3}$
is presented considering temperature dependent absorption coefficients
at 305 nm and 275 nm writing wavelengths. The extrapolated empirical relations
of absorption coefficient with temperature, extracted from the published experimental
data, is used for the purpose. Some of the previously published experimental
findings of the fabricated wave guides are justified with
this model, which otherwise seem impossible.
