ALL-OPTICAL RECONFIGURABLE CASCADABLE LOGIC WITH LINEAR PREPROCESSING BY LIGHTWAVE INTERFERENCE AND POST-PROCESSING BY NONLINEAR PHASE ERASURE
ALL-OPTICAL RECONFIGURABLE CASCADABLE LOGIC WITH LINEAR PREPROCESSING BY LIGHTWAVE INTERFERENCE AND POST-PROCESSING BY NONLINEAR PHASE ERASURE
The present invention introduces a new architecture for all-optical logic architecture. In this architecture the gate is partitioned into a linear front-end followed by a nonlinear back-end. The logic calculation is practically performed within the linear stage, easing the requirements placed on the non-linear part and thus reducing the gate complexity. The new structures provide flexibility and improved performance for the all-optical logic. The proposed scheme may be integrated optics/electronics. An important additional attribute of our all-optical logic family is reconfigurability, i.e. the ability of the hardware architecture or devices to rapidly alter the functionalities of its components and the interconnection between them as needed.
