Abstract
An overview is given of permanent changes in the refractive index and optical transmission which occur in some rare earth-doped inorganic glasses and optical fibers when resonantly excited into specific 4f and 5d manifolds. These phenomena are believed to be electronic in nature involving color centers. They are important for both refractive index grating devices as well as for the optical reliability of Er3+-doped optical fiber amplifiers.
