Abstract
TWO-DIMENSIONAL SPATIAL LIGHT MODULATORS (2DSLM) ARE KEY TO EVERY OPTICAL SIGNAL/COMPUTING ARCHITECTURE. HOWEVER, 2DSLMS HAVE NOT BEEN WELL DEVELOPED FOR PRACTICAL APPLICATIONS DUE TO A LACK OF HIGH QUALITY NONLINEAR OPTICAL (NLO) MATERIAL, AND INADEQUACIES IN THE DEVICE CONCEPT. CURRENT 2DSLMS GREATLY LIMIT THE DEVELOPMENT OF OPTICAL SIGNAL PROCESSING. RESEARCHERS ARE DEVELOPING AN INNOVATIVE, TWO-DIMENSIONAL OPTICALLY ADDRESSED, THRESHOLDING, AND ERASABLE 2DSLM. THE 2DSLM IS BASED ON A NONLINEAR FABRY-PEROT INTERFEROMETER MODULATOR WITH CAVITY MATERIAL MADE OF BACTERIORHODOPSIN (BR), A NEWLY DEVELOPED NONLINEAR OPTICAL (NLO) PHOTOCHROMIC PROTEIN. THE DEVICE UTILIZES THE LARGE REFRACTIVE INDEX CHANGE OF BR IN THE FABRY-PEROT CAVITY TO ALTER THE DEVICE OPTICAL TRANSMISSION. THIS DEVICE HAS EXCELLENT SPATIAL RESOLUTION, HIGH OPTICAL SENSITIVITY, EASY ERASABILITY, SIMPLE ADJUSTABLE THRESHOLDS, RANDOM ADDRESS CAPABILITY, ENORMOUS PIXEL DENSITY, AND HIGH CONTRAST. THE PROJECT IS A MAJOR BREAKTHROUGH IN THE REAL-TIME, HIGH-SPEED OPTICAL IMPLEMENTATION OF PATTERN RECOGNITION, OPTICAL COMPUTING, NEURAL NETWORK, AND NONLINEAR IMAGING PROCESSING. THE EFFORT CONSISTS OF ANALYTICAL AND EXPERIMENTAL WORK AIMED AT EVALUATING SPATIAL RESOLUTION, SENSITIVITY, WRITE/ERASE CYCLES, AND FABRICATION PROCEDURES OF THE BR-SLM.
