ABSTRACT:
A three dimensional memory having an increased storage capacity. The memory block has a matrix of cylindrical cavities, each of which has a fiber optic light guide means disposed therein. Each light guide means is comprised of a cylindrical core having a first index of refraction and a cladding surrounding the core having a second, smaller index of refraction; a plurality of spaced deformations are formed at the core-cladding interface for allowing light to leak out of the guide laterally.
