Holographic Polymer-Dispersed Liquid Crystals: Materials, Formation, and Applications
Figure 78
Diffraction efficiency as a function of incident angle for (a) -
and (b) -polarized light. The data is for a HPDLC
transmission grating with Λ 0.5 μm
probed at 632.8 nm. The grating thickness is about 10 μm. A fit to coupled-wave theory yields (a) = 0.125 (-polarization) and (b) = 0.048 (-polarization). High side lobe
indicates overmodulation.
