Holographic Storage Using BaTiO3 Fibers

LaserGenic's research addresses the need for materials for optical storage of information that solve limitations presently found in bulk photorefractive crystals. The structure of a monocrystal fiber increases the amount of information that can be stored by means of channeling the radiation along the fiber. Recently discovered storage properties of Fe:LiNbO3 fibers represent advances in this direction, because LiNbO3 has a longer index grating lifetime and a doubled figure of merit over other better known materials. Using the laser-heated pedestal-growth technique, LaserGenics will grow single crystal fibers of iron doped LiTaO3 because it is a material that has been studied extensively and its properties are well known. Fiber growth and test will ultimately lead to a working holographic storage system.
