Linear polarization-discriminatory state inverter fabricated by oblique angle deposition.

In this paper, we report a linear polarization-discriminatory state inverter made of three-layer sculpture thin film fabricated by oblique angle deposition technique. The first and third layers are quarter-wave plates of zigzag structure and the middle of them is a circular Bragg reflector of left-handed helical structure. It is found that the normal incidence of P-polarized light on this polarization-discriminatory state inverter becomes the S-polarized light at output, while the incident S-polarized light of wavelength lying in the Bragg regime is reflected. The microstructure of the linear polarization-discriminatory state inverter is also investigated by using a scanning electron microscope.

It is found that the bilayer circular filter reflects both right and left circularly polarized light with wavelength lying in the Bragg regime. The microstructure of the bilayer circular filter is also investigated using a scanning electron microscope.

Handedness inversion of circularly polarized light realized with helical and zigzag films fabricated by glancing angle deposition

Oblique angle deposition (OAD) is a sophisticated technique to fabricate engineered nanostructured thin films for next generation optical nanodevices. In this technique, oblique angle deposition and substrate rotation are employed to control the columnar and helical nanostructures of thin films. The films deposited by this technique show the optical anisotropy, the porosity, or the chirality, depending on the controlled morphologies at the nano-scale. In this review paper, the nanostructured optical thin film devices, such as a circular polarization handedness inverter, a linear polarization-discriminatory inverter and the selective coatings on nanopatterns, are fabricated by electron beam evaporation using the OAD technique, and their optical and structural properties as nanooptical devices are described.

In this study, a linear-polarization selector, made of a three-section sculptured thin film, is reported. Within the Bragg regime, the normal incident P-polarized light is transmitted through it, while the incident S-polarized light is reflected.
