PHOTOREFRACTIVE EFFECT IN A CONJUGATED POLYMER BASED MATERIAL

摘要

A new type of polymeric photorefractive material based on a conjugated polymer has been developed. Photorefractive effect was observed in a second order nonlinear optical polythiophene derivative with the addition of a photosensitizer. The linear and second order nonlinear optical properties, photoconductivity and photorefractivity for this material were investigated. Relatively two-beam-coupling gain coefficient of 24.5 cm(-1) was measured. [References: 24]
