Waveguides and Y junctions formed in bulk media by using dark spatial solitons.
Dark spatial solitons are created when intense quasi-plane waves containing amplitude or phase discontinuities propagate through self-defocusing, Kerr-like media. We show that dark solitons form not only stable waveguides but also structures equivalent to Y-junction splitters and other devices.
