Design and fabrication of circular-polarization separator using a glancing angle deposition (Helical structure)

경사입사 증착법 (나선형 구조)을 이용한 원편광 분리소자의 설계 및 제작

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). The optical porosity of $TiO_2$ film deposited by helical method can be applied many optical coatings.
