Fiber Optic Broadband Light Sources

ASE Sources - Fibotec Fiberoptics GmbH (FiboTEC)

Fiber optic broadband light sources use amplified spontaneous emission (ASE) within optically pumped rare earth doped fibers. The spectral width of the light source can be determined by the developer in a range of a few nm to the full width of the emission spectrum of the active ion (eg, erbium ion). The optical power density of fiber optic ASE sources is typically higher than that of fiber-coupled broadband semiconductor light sources with simultaneously lower intensity noise (RIN). These properties, and the lack of resonator interference, of good incoherence make ASE sources a preferred instrument for use in metrology applications.
