摘要:
The anisotropic multilayer thin-film coatings may be used in fabrication of various optical elements, such as polarizers, beam splitters, interference-polarizing light filters, polarizing mirrors, etc.A multilayer optically anisotropic structure, which contains at least one layer with high degree of anisotropy and perfect structure, whereas refraction indexes and thicknesses of all layers and their combination is selected such as to provide an intereference extremum for at least one polarization of light in the said region of the spectrum and on at least one side of the multilayer optical structure, wherein at least one of the layers is optically anistropic and has been made of at least one organic materiel, molecules or fragments of molecules of which have flat build and where at least a part of the said layer has crystalline structure, while the following relationships are true for the main axes of ellipsoids of the imaginary and the real parts of the refraction index of the anistropic layer in the region of at least one of the absorption bands of the layers’ material on the area with linear dimensions no less that wavelength of the maximum of the least one absorption band : K1 ≥ k2 > k3, (n1 + n2) / 2 > n3, where k1, k2, k3 and n1, n2, n3 - are the main values of the axes of ellipsoids of the imaginary and the real parts, accordingly, of the refraction index of the layer.
