Latest Patents

Among his latest innovations, Hall's work on "Azo-dye-doped photorefractive polymer composites for holographic testing" stands out. This groundbreaking photorefractive device consists of a layer of a novel composite that incorporates a photoconducting polymer, a photosensitizer, a unique second-order non-linear optical chromophore, and a plasticizer. The design allows the device to effectively internally store image patterns generated by the interference of two coherent light beams. The high diffraction efficiencies of nearly 100% and a substantial net two-coupling gain exceeding 200 cm⁻¹ make this composite suitable for read/write holographic storage applications. Notably, information writing is reversible, and the device can operate optimally at room temperature. The light source integrated within this invention utilizes semiconductor laser technology, while a commercial silicon photodiode or a CCD camera serves as a detector.

Additionally, Hall has developed alkyl vinylidene cyanide polymers that exhibit nonlinear optical and piezoelectric properties. These novel polymers have significant potential as media for various optical devices.
