L-band ASE broadband light source

L-band ASE broadband light source

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