The concept of an effective Verdet constant is proposed and experimentally validated. The effective Verdet constant of light propagation in a fiber includes contributions from the materials in both the core and the cladding. It is measured in a 25 wt . % terbium-doped-core phosphate fiber to be 6.2 ± 0.4 rad ( T m ) at 1053 nm , which is six times larger than silica fiber. The result agrees well with Faraday rotation theory in optical fiber.
