DK Photonics C band 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 light source wavelength covers the C-band (1528nm~1569nm), with spectral flatness better than 2dB. It is coupled and output through single-mode fiber, with continuously adjustable power and optional polarization maintaining fiber output for linear polarization. Suitable for applications such as fiber optic sensing, it can provide various forms of packaging.
