Distributed Feedback (DFB) Lasers

Distributed Feedback (DFB) LasersA Distributed Feedback Laser (DFB) refers to laser diodes or quantum cascade lasers (QCLs), for example, in which the surface of the active region or gain medium is etched with a periodic structure or diffraction grating (Bragg grating). This grating creates a one-dimensional interference grating, providing optical feedback. Essentially, this process allows only one wavelength to emit from the diode, rather than one center wavelength with a couple of lower power side wavelengths that you typically get from a standard Fabry-Perot laser diode. Distributed Feedback (DFB) Laser Diodes are single-frequency and offer a Narrow Linewidth with good side mode suppression ratio (SMSR).

Discreet-Mode (DM) Laser Diodes offer very similar performance to DFB Lasers. Discreet-Mode Laser Diodes are produced with a simple and low-cost fabrication process and have many advantages. For example, they have very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.
