Latest Patents
Hagan's latest patents focus on switchable polymer-dispersed liquid crystal optical elements. These patents describe how transmission and reflection type holograms can be formed using a novel polymer-dispersed liquid crystal (PDLC) material. This unique material possesses switching characteristics that allow for the creation of optical elements. The applications for these switchable holograms include communications switches and switchable lenses in red, green, and blue. The PDLC material combines the features of holographic photopolymers with the added advantage of being able to switch the hologram on and off with an electric field. The composition includes a polymerizable monomer, liquid crystal, and a photoinitiator dye. Upon irradiation, the liquid crystal separates into nanometer-sized droplets, which align in periodic channels to form the hologram. This innovative material is referred to as holographic polymer-dispersed liquid crystal (H-PDLC).
