L-band ASE Broadband Light Source

Fiber ASE broadband light source belongs to incoherent light source, which is the spontaneous emission generated by erbium-doped quartz fiber pumped by semiconductor laser. At the same time, spectral flattening technology is introduced to realize broadband flattening spectrum. The light source wavelength covers the 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 optical fiber sensing and other applications.
