Mechanisms of Photorefractivity in Polymeric Materials

Abstract

This grant features a dual-edged effort of physical measurement (at Stanford) and synthesis (at the Kent State subcontractor) to develop new photorefractive polymers, demonstrate previously unobserved physical effects, and most importantly, to understand the mechanisms controlling the performance. This collaboration between Stanford and Kent, has successfully developed several new classes of materials which have been explored in detail using thermal, optical, electrical, and photorefractive measurements. Using our faster materials, we have demonstrated two new applications for photorefractive polymers: image amplification/novelty filtering, near-infrared response in a glassy photorefractive, and adaptive beamsplitting for detection of laser-generated ultrasound.
