Circular-polarization separator deposited by glancing angle deposition for display system

In this study, the optical porosity of TiO
₂
films with helical structure deposited by glancing angle deposition (GLAD) were investigated. Helical films are of interest due to their ability to differentiate states of circularly polarized light. We designed and fabricated normal-incidence circular-polarization separator deposited by GLAD (helical structure).
