C-band ASE light source module 1550nm 10mW

ASE light source is a white light source that has very high brightness over a very wide spectral range. The C-band ASE wide spectral range light source module is an amplified spontaneous emission (ASE) light source used in distributed fiber Bragg grating sensing systems, optical passive device testing, and spectral analysis design. Based on the basic principle of semiconductor laser pumped rare earth doped fiber (Er ion) to generate C-band (1528-1563nm) amplified spontaneous emission (ASE), a specially designed C-band spectral gain flattening filter (GFF) structure enables the product to have high optical to optical conversion efficiency and excellent C-band spectral flatness. At the same time, to ensure the strict requirements of the distributed fiber Bragg grating system for the stability of the light source output, global optical feedback control technology and pulse width modulation (PWM) precision temperature control technology are adopted internally to ensure high output optical power stability and spectral waveform stability.
