Optical fibers doped with rare earth elements have potential application as passive fiber devices through their ability to rotate the plane of polarization in the presence of a magnetic field. Such devices have use not only as sensors of electric and magnetic fields but also as fiber lasers for a host of applications. The Laboratory for Lightwave Technology, in conjunction with the Dept. of Chemistry, has engaged in a program of the study of rare earth elements in fibers, and in bulk glasses as well. Some of the first rare earth glasses made with the sol-gel technique come from this research.
