Summary: 
Phase-matched film thickness are studied precisely for SHG in a nonlinear quartz-glass waveguide. The glass film waveguide deposited upon the surface of quartz suffers non-uniform stress due to the thermal expansion. This effect generates an anisotropic property in the film. Taking this anisotropy of the glass film into account, the observed film thickness for phase-matched condition results in good agreement with the theory.
