Abstract

An optical limiter based on a large birefringence which is optically induced in bacteriorhodopsin is presented. The induced birefringence is observed to be a function of incident intensity, but saturates at a value of about 0.454 W/cm². A measured value of (Delta) n of 6.6 multiplied by 10^-4 at wavelength of 514 nm is reported. The observed birefringence is found to be in good agreement with a proposed model based on vector-tensor approach.
