L-band ASE broadband light source 1567-1603nm@2dB

Fiber ASE broadband light source belongs to incoherent light source, which is the spontaneous emission generated by semiconductor laser pumped erbium-doped quartz fiber. At the same time, spectral flattening technology is introduced to achieve broadband flattening spectrum. The light source wavelength covers the L-band, with a spectral flatness of better than 3dB. It is output through single-mode fiber or polarization maintaining fiber and is suitable for applications such as fiber optic sensing.
