Paper Abstract

In photorefractive polymers, higher order diffraction and energy exchange are analyzed in two wave coupling configuration. The dependence of the second-order diffraction on the two-wave intensity ratio was simulated and investigated experimentally. The maximum value second- order intensity increases with increasing applied voltage, however for energy exchange of photorefractive polymer, beam ratio for the maximum second-order intensity shift from equal beam intensity. Using this programmable edge enhancement can be obtained by changing the voltage and incident beam intensity ratio.
