| Popis: | In this work, a polarization grating in Raman-Nath regime was fabricated by using a photoreactive polymer liquid crystal exhibiting biaxial optical anisotropy. And from the measured characteristics, it has been demonstrated that the flat incident angle dependences on diffraction efficiency and polarization ellipticity are obtained by introducing biaxial optical anisotropy. |
