ASE Broadband light source
The fiber ASE broadband source is incoherent, using spontaneous emission from erbium-doped silica fiber pumped by a semiconductor laser. It covers the C band (1528nm~1568nm) with spectral flatness of 20dB, single-mode fiber-coupled output, and continuously adjustable power. Optional polarization-maintaining fiber provides linearly polarized output. It suits fiber sensing and is available in various packages.
