Inphenix’s #dfblaser has a simple and low-cost fabrication process and has many advantages, such as a very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.

Distributed Feedback Laser (DFB Laser) is an edge-emitting semiconductor light source. Compared to #fplasers, DFB Lasers are much more stable.

Major Difference Between DFB Laser And DBR Laser

A DFB laser is a type of diode laser that generates resonance and oscillation in the cavity using diffraction gratings rather than mirrors. The laser’s purpose is to sharpen the output of conventional #FPlasers.

In comparison to the #DFBlaser, the DBR laser generates single frequency, phase coherent photons at a specific wavelength.
