Distributed Feedback Laser (DFB)

Distributed Feedback Laser (DFB)

Optical Spectral Engine (OSE3)

  • 1–5 MHz Linewidth

  • 1530–1610nm ITU grid coverage

  • Integrated, high-power fiber output

DAYY Photonics Corporation Distributed Feedback Laser (DFB) product family covers a large selection of wavelengths ranging from 1530nm-1610nm. Center wavelengths covering the full ITU grid for DWDM systems are covered. The DFB laser module is also ideal for gas detection applications such as tunable diode laser spectroscopy or cavity ring down spectroscopy.

Our light source product family comes in a hermetically sealed 14-pin butterfly package or TO-Can package style. The laser diodes contains thermoelectric cooler (TEC), thermistor, monitor photodiode and optical isolator to secure high quality laser performance.

The light source meets Telcordia GR-468 standard and is RoHS/Reach compliant.
