The parameters of the optical slab glass waveguide (refractive index and thickness of thin film) were measured by a new technique for using the prism coupler, i. e., leaky mode method.

The polarization characteristics of the corner-cube prism for YAG laser are analyzed, and two kinds of optical thin films are designed to compensate its polarization properties.
The Fourier spectral analysis method is applied to the input-output coupling problem of a prism-thin film waveguide system. The input-output coupling equations are solved fast and exactly.
