A time-dependent theoretical model based on the rate equations for all the photochemical states of bacteriorhodopsin (bR) isdeveloped. A recursive method is adopted to solve the rate equations exactly, with an explicit temporal and intensity dependenceof the population densities. Simulated results for a thin wild type bR lm show that each intermediate state has a optimum popu-lation that depends uniquely on incident intensity and time. The model provides an analytical framework for optimization of bR forvarious electronics and photonic applications.. 2004 Elsevier B.V. All rights reserved.PACS:42.70.Gi; 82.39.Rt; 87.15.Aa; 87.14.Ee
