1550nm C-band High Stability ASE Light Source Module

The ASE light source is a white light source with very high brightness across a wide spectral range. The C-band ASE wide-spectrum light source module is used in distributed fiber Bragg grating (FBG) sensing systems, optical passive component testing, and spectral analysis design. It is an Amplified Spontaneous Emission (ASE) light source, which is based on the principle of pumping an erbium-doped fiber (Er ions) with a semiconductor laser to generate ASE in the C-band (1528-1563nm). Specially designed C-band spectral gain flattening filters (GFF) give the product extremely high optical-to-optical conversion efficiency and excellent spectral flatness in the C-band. To ensure that the distributed fiber Bragg grating system meets strict output stability requirements, global optical feedback control technology and pulse width modulation (PWM) precise temperature control are used internally. This ensures extremely high output power stability and spectral waveform stability.
