摘要：

Fully three-dimensional spatial solitons in bulk nematic liquid crystals form self-consistent waveguides that are able to confine a weak, collinear copolarized signal at different wavelengths and with large trapping angles. We use a milliwatt cw source to generate a soliton and, by angular steering of the soliton, spatially readdress the guided signal. (C) 2001 Optical Society of America.
