20mW C-Band ASE Broadband Light Source with Polarization-Maintaining Fiber Optic ASE-C-20-T-PM-B Desktop Type
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-band, and the spectral flatness is better than 2dB. It is output through single-mode fiber or polarization-maintaining fiber, which is suitable for applications such as fiber sensing.
