TLDR
A reconfigurable optical directed logic architecture that offers several significant improvements over the original directed logic presented by Hardy and Shamir is presented.Abstract:
We present a reconfigurable optical directed logic architecture that offers several significant improvements over the original directed logic presented by Hardy and Shamir. Specific embodiments of on-chip, waveguided, large-scale-integrated, cellular optical directed logic fabrics are proposed and analyzed. Five important logic functions are presented as examples to show that the same switch fabric can be reconfigured to perform different logic functions.read more
