Iceland DFB Distributed Feedback Laser 40G
Covering NIR to LWIR wavelengths (750nm–17µm), these lasers feature integrated DFB gratings and TEC cooling for robust thermal management and low-noise performance across diverse conditions. A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. This grating acts as a diffraction element that selectively reinforces a specific wavelength, resulting in. The acronym DFB laser stands for distributed feedback laser. Their key features relative to other semiconductor lasers are their single longitudinal mode (single frequency) emission profile, their high stability and their wavelength tunability. Typically, the periodic structure is made with a phase shift in its middle. They are used for high-performance gas sensing applying tunable diode laser spectroscopy. nanoplus lasers operate reliably in more than 100,000 installations worldwide.
