About: Erbium-doped waveguide amplifier

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

An erbium-doped waveguide amplifier (or EDWA) is a type of an optical amplifier. It is a close relative of an EDFA, Erbium-doped fiber amplifier, and in fact EDWA's basic operating principles are identical to those of the EDFA. Both of them can be used to amplify infrared light at wavelengths in optical communication bands between 1500 and 1600 nm. However, whereas an EDFA is made using a free-standing fiber, an EDWA is typically produced on a planar substrate, sometimes in ways that are very similar to the methods used in electronic integrated circuit manufacturing. Therefore, the main advantage of EDWAs over EDFAs lies in their potential to be intimately integrated with other optical components on the same planar substrate and thus making EDFAs unnecessary.
