C-band ASE broadband light source gain flat modular/desktop

The C-band gain flattened fiber ASE broadband light source module adds gain flattening technology to the ordinary broadband light source and optimizes the light source structure. The output spectral flatness reaches 2dB, while having high output power and miniaturized external dimensions. 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 wavelength of the light source covers the traditional C-band (1529.16nm~1560.61nm, frequency 195.9THz~191.6THz), with spectral flatness better than 2dB. It is output through single-mode fiber or polarization maintaining fiber and is suitable for applications such as fiber optic sensing.
