Abstract:

We report on spatial soliton formation and self/cross-waveguiding in planar cells containing a nematic liquid crystal in the presence of an externally applied voltage. Self-confinement and cross-induced guidance are demonstrated with an Argon ion laser (514nm) and a Helium-Neon probe (633nm), respectively, over mm lengths and with mW pump powers.
