Fiberoptic Broadband Light Sources

Key Features

  • Extremely high power stability
  • Wavelength shaping
  • Additional 1060 nmversions


Fiberoptic broadband light sources make use of the Amplified Spontaneous Emission (ASE) within optically pumped rare-earth-doped fibers. The spectral width of such light sources ranges by design from a few nm to the entire emission wavelength range of the dopand (e.g. erbium ions).

The optical power density of fiberoptical ASE-source is typically higher than that of broadband fibercoupled semiconductor based devices at an even lower noise level (RIN). This characteristic and the strong incoherence due to the absence of residual resonator effects make ASE-sources an ideal instrument in test and measurement applications.


C- and L-band sources are utilized for spectral characterization of optical components including the DWDM-market. Applications are also found in various White Light Interferometer based measuring instruments
