L Band ASE Broadband light source
The fiber ASE broadband source is incoherent, using spontaneous emission from erbium-doped silica fiber pumped by a semiconductor laser. Spectral-flattening technology provides a flat broadband spectrum covering the L band, with spectral flatness better than 2.5dB. It provides single-mode or polarization-maintaining fiber output for fiber sensing and related applications.
