Anisotropic optical waveguides in some cases can connect between each other external light beams and waveguide optical fields without any additional coupling elements, only due to existing of leaky optical waves in such waveguides. Because of the simplest design anisotropic waveguides with light leakage can be used in many integrated-optical elements including waveguide sensors. Some features of leaky wave excitation in planar waveguides LiNbO3:Ti and H+:LiNbO3 while total internal reflection of ordinary polarized light beams from a waveguide boundary have been experimentally investigated in this work. Besides, an influence of temperature changing on coupling angle variations at such excitation method has been considered as well with regard to possible applications of similar elements in integrated optics.
