ASE(Amplified Spontaneous Emission) Light Source Module 20mW C-band Broadband Laser SM Fiber ASE-C-20-T-SM-M
The fiber ASE broadband light source is an incoherent light source. It is the spontaneous radiation generated by semiconductor laser pumping erbium-doped quartz fiber. At the same time, the spectrum flattening technology is introduced to achieve broadband flat spectrum. The wavelength of the light source covers the C band (1528nm~1569nm), the spectrum flatness is better than 2dB, and the output is coupled through a single-mode fiber. The power is continuously adjustable, and the polarization-maintaining fiber output linear polarization can be selected. It is suitable for applications such as fiber optic sensing.
