Laser Diodes & Sources
The ASE (Amplified Spontaneous Emission) light source series provides a singlemode broadband emission with low coherence and randomized polarization, making it ideal for high-precision measurement applications. The design utilizes rare-earth-doped fibers pumped by a cooled laser source, enhancing longevity and reliability. Featuring precision feedback control, the unit ensures high stability. The ASE 1550 is available in two wavelength bandwidth configurations: C-band (1528–1563 nm) and C+L band (1528–1615 nm). We offer both OEM modules with a driving PCB and plug-and-play benchtop units. A flat version integrates special filters for a flat spectral output to meet specialized application needs in the C-band. The ASE is also an excellent polarization light source with a high and stable polarization extinction ratio.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
ASE 1550nm Broadband Light Sources: Laboratory optical integration depends on preserving the optical budget through the complete path. The C, C+L, Special wavelength specification sets source and detector compatibility. The fiber/interface entry (None, FC/PC, FC/APC, SC/PC, SC/APC, LC/PC, LC/APC, LC/UPC, Special) must match the connected components.

Technical FAQ
Interface: Non, USB, RS232 · Connector: None, FC/PC, FC/APC, SC/PC, SC/APC, LC/PC, LC/APC, LC/UPC, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: C, C+L, Special. Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
