An optically addressed spatial light modulator that is based on the chemically enhanced bacteriorhodopsin thin film is demonstrated. The underlying principle is the light-induced shift of absorption band of the protein. The device can be chemically or genetically modified for different applications. In our preliminary experiment, a resolution of about 100 line pairs per millimeter with a linear dynamic range of above 100:1 is obtained.
