Rare-Earth Metal

There are two series of rare-earth metals, the Lanthanides and Actinides. The latter contains elements 89-103, many of which are radioactive, such as Uranium and Plutonium. To fiber optics, the Lanthanide series (containing elements 57 to 71) is of most interest, as many of these elements have ionic absorption bands in and around the infrared spectrum, which corresponds with the transmission window of optical fibers. Fibercore manufacture fibers doped with a choice of Neodymium, Erbium and Ytterbium.
