Laser Diodes & Sources
The DFBD series fiber-coupled laser diodes are designed with a GaAs quantum well structure integrated with a grating configuration. These diodes feature a built-in photodiode for precise monitoring and feedback control of the laser’s output power. Housed in standard TO packages, these diodes are pigtailed to a 1-meter long single-mode fiber terminated with an FC/APC connector. Each unit undergoes rigorous testing prior to shipment to ensure reliability. Additionally, we offer a cost-effective, high-performance feedback control driver kit that maintains constant and adjustable output power, along with an externally cooled mounting fixture to stabilize the output wavelength. It is available in module or benchtop.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
1568nm DFB Laser for Gas Sensor: Laboratory optical integration depends on preserving the optical budget through the complete path. The 1564nm wavelength specification sets source and detector compatibility. The fiber/interface entry (SM28, PM1550, PM1310) must match the connected components.

Technical FAQ
Fiber Type: SM28, PM1550, PM1310 · Fiber Buffer: 0.9mm Tube. 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: 1564nm. 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.
