Abstract
We have fabricated 1-, 2- and 3-D photonic crystalline structures in polymer dispersed nematic and isotropic phase liquid crystals. It is observed that a particular mixture of isotropic liquid crystals and the photo-polymer will also polymerize and phase separate, forming high quality optical gratings, just as typical nematic liquid crystals. Liquid crystal droplet sizes obtained could be as small as a few 10's of nm, i.e., nano-droplets. The resultant structure exhibits excellent optical qualities, and high efficiency Bragg diffraction properties.
