Enhanced magneto-optical effect in cobalt nanoparticle-doped optical fiber

摘要

An enhanced magnetic Faraday effect is demonstrated in cobalt nanoparticle-doped polymer optical fiber. Magneto-optically induced rotation of the plane of polarization proportional to both the dopant particle concentration and the magnetic field strength is demonstrated. Potential applications include magnetic field sensors, current sensors, and in-fiber optical isolators.
