PROBLEM TO BE SOLVED: To provide a method of enhancing polarization conversion reflection from an anisotropic thin film. SOLUTION: Total reflection effect or high reflection at an interface of the anisotropic thin film causes enhancement of polarization conversion. The polarization conversion is an interesting phenomenon, by which a fraction of p(s)-polarized light incident on the anisotropic thin film is reflected as an s(p)-polarized light. In a method that can make the anisotropic thin film generating high reflection or total reflection, (1) the reflection coefficients of the rays, reflected internally inside the anisotropic film, can be raised, by arranging a high-refractive incident medium and a low-refractive substrate and (2) the characteristics that the anisotropic thin film with at least two different principal indices of refraction and the characteristics that principal axes coordinates do not coincide with the film surface coordinates are useful for polarization conversion. The phenomenon of the polarization conversion could be obtained by changing the aspect of an incident plane. COPYRIGHT: (C)2007,JPO&INPIT
