Narrow band incoherent optical carrier generator

摘要: A narrow bandwidth incoherent optical source is provided. superluminescent includes a gain medium having an input end and output end. The of the optically coupled to reflector cause spontaneous emissions within predetermined band exiting be reflected back into medium. Spontaneous outside are lost. can comprise doped fiber, such as Erbium fiber. An isolator prevents from lasing. By providing plurality reflectors operating in different bands, generate carriers.
