Explicit construction of single input - single output logic gates from three soliton solution of Manakov system

摘要

We construct single input logic gates using the energy sharing collisions ofa minimal number of (three) bright optical solitons associated with the threesoliton solution of the integrable Manakov system. As computation requiresstate changes to represent binary logic, here we make use of the state changeof a particular soliton during its sequential collision with other two solitonsfor constructing single input gates. As a consequence, we clearly demonstratethe construction of various one-input logic gates such as COPY gate, NOT gateand ONE gate using energy sharing three soliton collision of Manakov system.This type of realization of logic gates just from a three soliton collision(pair-wise interaction) is clearly distinct from the earlier studies whichrequire separate collisions of four solitons.
