The photodeflection method applied to the propagation losses characterization in channel waveguides is discussed using two different set-up configurations. 3D and 1D models are presented in order to calculate the photodeflection angle. The effects on the measurement of set-up misalignments are studied. Different ways for determining the propagation losses are shown. Comparison between theoretical and experimental results for Ti:LiNbO3 and a glass channel waveguide is also reported. The method has proven suitable to measure losses as low as 0.2 dB/cm. |
