Holographic photopolymerization is a flexible, simple, one-step technique t
o create defect-free, sub-micrometer patterns of particles over large dimen
sions. These permanent structures can be formed in a matter of seconds. The
resulting, Bragg gratings exhibit substantial diffraction efficiencies. Th
e Figure shows a cross-sectional fracture surface of a transmission grating
formed using clay powder.
