The feasibility of building writeable and erasable waveguides and thin film optical elements in photodichroic materials was examined. The studies involved consideration of controllable deflection or focal length using the photodichroism of color centers in alkali-halide crystals. Material properties limiting the ultimate application and areas needing further research were identified.
