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. The structure builds a one-dimensional interference grating (Bragg scattering), and the. Distributed feedback (DFB) lasers employ a periodic grating within or adjacent to the gain medium to enforce single‐mode emission and suppress competing resonances. By embedding a Bragg grating directly into the semiconductor waveguide, DFB devices achieve stable wavelength control, narrow spectral. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height).
