Abstract

We introduce optical isolation based on reorientational solitary waves in nonuniformly oriented uniaxial soft matter, namely nematic liquid crystals. A longitudinally nonsymmetric angular distribution of the optic axis provides the system with direction-dependent routing, resulting in an all-optical diode owing to input-side sensitive steering. Numerical experiments demonstrate the phenomenon and its effectiveness in realistic samples.
