This time we explained the C+L Band 100mW ASE broadband light source in our laboratory. The wavelength range is 1528nm~1603nm. The power can be adjusted by the button, and the adjustment accuracy is 1mW. The adjustment range is 10%~100%. We need to use infrared photosensitive film to observe the light spot of the laser in this band. Let’s check it now.
The test data report of this ASE broadband light source.
The fiber ASE broadband light source is an incoherent light source, which is the spontaneous radiation generated by the semiconductor laser pumping erbium-doped silica fiber, and the spectral flattening technology is introduced to achieve a broadband flat spectrum. The wavelength of the light source covers the C+L band, and the spectral flatness is better than 3dB. It is output through single-mode fiber or polarization-maintaining fiber, which is suitable for applications such as fiber sensing.
