DK Photonics C-band ASE Broad-band Light Source Module(Low flatness) belongs to incoherent light source, which is the spontaneous emission generated by semiconductor laser pumped erbium-doped quartz fiber. The light source wavelength covers the C-band, with a spectral flatness of better than 7dB, and is coupled with single-mode fiber output. Suitable for applications such as fiber optic sensing, it can provide two forms of packaging.
