Abstract:

We describe a birefringent thin film as a waveplate for polarization conversion, a system of birefringent thin films for photonics bandgaps and achromatization of functionality, birefringent thin film with a twist and multilayer CDW coatings. A theory of a broadband thin-film polarizing beam splitter based on an anisotropic cycloidal diffraction grating is proposed. The achromatization of the grating is provided by creating two-layer chiral structures with an opposite twist sense. Such a system has almost 100% efficiency. The calculations were carried out by the Jones matrix method. The resulting efficiency and bandwidth are higher than the previously known results.
