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 laser) is a laser where the whole resonator consists of a periodic structure in the laser gain medium, which acts as a distributed Bragg reflector in the wavelength range of laser action. Because the reflectivity is wavelength independent, typically the emis-sion from an edge-emitting Fabry-Perot device has many peaks in a range of 15 nm or so (see Fig. The structure builds a one-dimensional interference grating (Bragg scattering), and the. The acronym DFB laser stands for distributed feedback laser. The most mature and widely deployed wavelength is 850 nm. A typical VCSEL spectrum is shown below: Figure 1 VCSEL Spectrogram VCSEL lasers exhibit the following spectral features: • VCSELs operate in multiple transverse modes, producing a.
