Harnessing energy sharing collisions of Manakov solitons to implement universal NOR and OR logic gates

Abstract

The energy sharing collision of bright optical solitons in the Manakov system, governing pulse propagation in high birefringent fiber, is employed theoretically to realize optical logic gates. Especially, for the first time, we successfully construct (theoretically) the universal NOR gate and the OR gate from the energy sharing collisions of just four bright solitons which can be well described by the exact bright four-soliton solution of the Manakov system. This construction procedure has the important merits like realizing the two input gates with a minimal number of soliton collisions and possibilities of multi-state logic. The recent experiments on Manakov solitons suggest the possibility of implementation of this theoretical construction of such gates and ultimately an all optical computer.
