Design of micro-ring resonator-based all-optical logic shifter

Recently there has been great interest in using the nonlinear property of optical micro-ring resonator for all-optical switching. An all-optical logic shifter circuit with the help of GaAs-AlGaAs based micro-ring resonator is proposed and described. In the present paper the advantages of ring resonator based switch have been exploited to design an integrated all-optical circuit which can perform the logical operations left shift, right shift, circular left shift and circular right shift. Numerical simulation results confirming described methods are given in this paper.
