All-optical switching by Kerr nonlinear prism and its application to of binary-to-gray-to-binary code conversion

Nonlinear optics deals with numerous physical phenomena associated with nonlinear cubic susceptibility. In this paper, we have proposed an all-optical switching principle using Kerr effect considering the passage of optical wave through a prism made of non-linear material like fused silica. The performances of the optical switch as well as its various properties were also done by numerical simulation. Furthermore, we also proposed all-optical binary-to-Gray and Gary-to-binary (radix 2) code convertor circuits by this proposed architecture.

► All-optical switching using Kerr effect in a non-linear prism is proposed. ► Numerical simulation confirms feasibility of scheme. ► Binary-to-Gray and Gary-to-binary conversion circuits by this switch are also given.
