A new class of optical, switching and memory devices is based on the different refractive indices associated with each of the two states of the reversible photochemical interconversion between dimer and monomer states in a broad class of organic materials. Reversibility is expedited by use of a rigid medium. The active material may be a solution or suspension of the photosensitive species in a transparent matrix or may be a single-crystal form of the photosensitive material itself.
