Holographic Polymer-Dispersed Liquid Crystals: Materials, Formation, and Applications

<table>Diffraction efficiency versus the electric field curves for Bragg gratings made
of liquid crystal E7 with three different kinds of surfactants, octanoic acid (no. 1),
S-271 POE sorbitan monooleate (no. 2), and Tergital Min-Foam 1X (no. 3),
respectively. The diffraction efficiency without surfactant is also shown for
comparison.</table>
