Nematicons in twisted liquid crystals

In this work we demonstrate the properties of spatial solitary waves (nematicons) in a twisted nematic liquid crystalline film. Such self-trapped beams were created due to optical reorientation nonlinearity for a light power of a few tenths of milliwats at the distances of a few millimeters. Additionally, it was demonstrated that a weak signal beam can be guided in a channel formed by a nematicon.
