Abstract
Strong asymmetry in the charge distribution supporting a single noninteract ing spatial needle soliton in a paraelectric photorefractive is directly ob served by means of electroholographic readout. Whereas in trapping conditio ns a quasi-circular wave is supported, the underlying double-dipolar struct ure can be made to support two distinct propagation modes. (C) 2001 Optical Society of America
