We realized optical logic gates using a bacteriorhodopsin (bR) doped polymer film. The bR undergoes a complex photocycle characterized by several spectroscopically distinct intermediate states. We realized optical logic gates using a He-Ne laser (632.8 nm) and a He-Cd laser (413 nm) that consider B-state and absorption change of M-state in the photocycle of bR. Also, we realized high speed AND logic gate using He-Ne laser (632.8 nm) and the second harmonics at 532 nm from a pulsed Nd-YAG laser that considering absorption spectrum between B-state and K-state.
