Self-Guiding, Spatial Soliton, and Pattern Formation

Self-Guiding, Spatial Soliton, and Pattern Formation 

In this context, nematic liquid crystals offer themselves as attractive candidates as the test beds for theories, concepts, and prototype device demonstrations as the millisecond response speed allow convenient dynamical observations, and actual practical solutions where there are less stringent requirements on the speed. An exemplary experimental observation of self-guiding effect in NLC is discussed here. 

Consider the case of a linearly polarized laser that is incident from the side window. If we denote its optical electric field hyA=A x and its direction of propagation is along z in a bulk NLC, the evolution of the amplitude of this optical field is described by a Schrbdinger-like equation in a slightly inhomogeneous medirrm  

Such fundamental sohton characteristics as well as other more sophisticated phenomena, including beam steering, beam combining, and incoherent fight processing.
