Abstract
The purpose of this paper is to present an all-optical EXOR for cryptographic application based on spatial soliton beams. The device is based on the propagation and interactions properties of spatial soliton in a Kerr nonlinear material. The interaction force between parallel soliton beam is analyzed from the analytical point of view and an exact solution is presented.
Highlights
Spatial solitons are optical beams that propagate without changing their shape, thanks to the balance between nonlinear effect and diffraction [1]

Summary
Spatial solitons are optical beams that propagate without changing their shape, thanks to the balance between nonlinear effect (self-focusing) and diffraction [1]. This balance effect has demonstrated to be stable in two-dimensional waveguides. Propagation and interaction properties of spatial solitons are extremely interesting and useful in order to allow and realize all-optical devices, thanks to their robustness to the external disturbs. In this paper an all-optical EXOR for cryptographic application is proposed. The device is based on two peculiar properties of spatial soliton: swing effect [6,7] and interaction between parallel soliton beams
