Paper Abstract

The photodeflection method is able to characterize the propagation losses in optical waveguides. The theory of the transverse configurations in air and in situ is reviewed. The procedure to determine the propagation loss coefficient is widely discussed. The experimental results on two different Ti:LiNbO3 and glass channel waveguides are in good agreement with theory.
