Abstract

Some damages may occur when sensitive BSO (Bi₁₂SiO₂₀) asymmetric spatial light modulators operate in some given modes, even though the power of the writing light beam is far less than the optical damage threshold. According to some experimental results and corresponding analysis, high voltage and given operating modes may lead to too high intensity photocurrent pulse in short time, consequently large quantity of heat in ultra-small area may make the narrow areas swell up and thus the damage of the BSO film. In order to get well sensibility, well resolution and well response speed without damages of the spatial light modulators, optimizing the structure parameters and the operating modes is necessary.
