self-focusing fiber self-focusing fiber[¦self ′fō·kə·siŋ ′fī·bər] (optics) A type of optical fiber in which the refractive index decreases continuously along the radius, but progressively more rapidly with distance from the radius, so that light rays which travel longer distances are speeded up, and nearly all light rays travel with the same net axial velocity. |
