— A 3‐D array of helical structures fabricated using holographic polymer‐dispersed liquid crystals (H‐PDLC) is presented. Multiple coherent beams are interfered to create a constructive helical pattern which is permanently captured using the standard H‐PDLC method. Films with such array of helical structures have both diffractive and circular polarization sensitive reflective properties. Iso‐intensity patterns, design parameters, fabrication process, optical/electro‐optical performance of these periodic helical structures are discussed along with their potential application for advanced electro‐optical devices.
