C Band ASE Broadband light source ( Standard version )
The standard C-band ASE broadband source is an incoherent source using spontaneous emission from semiconductor-laser-pumped erbium-doped silica fiber. Spectral flattening produces a broad, flat spectrum over the C band (1528nm~1569nm), with flatness better than 2dB. Single-mode fiber-coupled output has continuously adjustable power; optional polarization-maintaining fiber provides linearly polarized output. Suitable for fiber sensing and related applications, it is available in several packages.
