Distributed Feedback Lasers(DFBs)

DFB laser
Distributed Feedback Laser (DFB Laser) is an edge-emitting semiconductor light source. Compared to FP Lasers and DBR Lasers, DFB Lasers are much more stable and generate a clean single mode output. This is achieved by the inclusion of a diffraction grating along the active region of the chip. Inphenix’s DFB have a simple and low-cost fabrication process and have many advantages, such as very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.
