Abstract

The oscillations about the fiber axis that generally accompany a beam injected eccentrically into a gradient-index fiber can be substantially suppressed. It is shown how the constraint of Liouville’s theorem, which was thought to preclude this effect, is satisfied in a system of two coupled fibers. The length of the coupled-fiber section required for operation is found.
