Abstract : The Army requires high performance optical devices to meet diverse requirements in such areas as fire control, target recognition, laser eve protection and communications. Present devices are limited by the availability of photonic materials. To meet this need for photonic materials that have superior photochromic, photoelectric, or nonlinear optical (NLO) characteristics, we have been developing a new family of materials based on the protein bacteriorhodopsin (BR). This is a unique biological material which has promising photonic properties needed for diverse device applications such as: optical holographic memory (1), artificial photoreceptors (2), optical switches and frequency doublers (3). Genetic methods are used to produce these new BR based materials. The major objectives of this program are to gain insight as to how amino acid substitution affects photonic properties and to use these insights to identify which BR mutants have the most useful photonic properties.
