Abstract |
| One-dimensional multiplexed anisotropic gratings were fabricated in photoreactive polymer liquid crystals (PPLCs), and the diffraction properties were characterized. Based on the holographic technique, the overwriting process is combined with the highly-stable and -controllable molecular alignment of the PPLCs. As a result, 1st- and 2nd-order diffraction intensities variable gratings dependent on the polarization direction of probe beam were obtained without significant changing their total diffraction intensity. The multiplexed gratings can be used as polarization-selective diffractive optical elements. |
