Sharp waveguide bends induced by spatial solitons
- Universite libre de Bruxelles, Service d'optique et acoustique, B-1050 Brussels (Belgium)
We experimentally demonstrate the ability of a self-guided laser beam to induce waveguides with sharp bends. The beam is a two-dimensional photorefractive screening-photovoltaic bright spatial soliton generated inside a biased lithium-niobate crystal shaped as a prism. The soliton robustness against total internal reflections is shown to leave place to a low-loss unimodal waveguide undergoing multiple zero-radius 90 deg. turns.
