ABSTRACT:
An optical waveguide fiber having a high threshold for stimulated Brillouin scattering (SBS). The SBS threshold is increased by an acoustically antiguiding configuration of the fiber. An acoustic configuration comprises one or more acoustic regions having acoustic velocities decreasing from the centerline of the fiber. More preferable configurations have acoustic regions with smaller radial thickness and smaller differences in acoustic velocities among regions.
