This paper aims to propose a new all-optical implementation of Fredkin gate using micro-ring resonator (MRR) based logical switches. The proposed all-optical Fredkin gate scheme employs only five MRRs connected in a parallel branch topology, therefore found very compact and ultrafast as compared to many previously reported designs. The presented gate enjoys all-optical operation with no requirement for an additional wavelength converter. A detailed discussion of the all-optical switching mechanism of MRR has been presented and the logical behavior of the presented Fredkin gate has been demonstrated by using MATLAB simulations.

Abstract


This paper aims to propose a new all-optical implementation of Fredkin gate using micro-ring resonator (MRR) based logical switches. The proposed all-optical Fredkin gate scheme employs only five MRRs connected in a parallel branch topology, therefore found very compact and ultrafast as compared to many previously reported designs. The presented gate enjoys all-optical operation with no requirement for an additional wavelength converter. A detailed discussion of the all-optical switching mechanism of MRR has been presented and the logical behavior of the presented Fredkin gate has been demonstrated by using MATLAB simulations.
