C+L-band ASE Broadband Light Source
Product Overview
Fholink's Fiber ASE Broadband Light Source is an incoherent light source based on spontaneous emission generated by pumping erbium-doped silica fiber with a semiconductor laser. It incorporates spectral flattening technology to achieve a broadband flat spectrum. The light source covers the C+L-band with excellent spectral flatness 3 dB. Output is available via single-mode fiber or polarization-maintaining fiber, making it suitable for applications such as optical fiber sensing.
