Distributed Feedback (DFB) Lasers

What are Distributed Feedback (DFB) Laser Diodes?

A Distributed Feedback (DFB) Laser Diode is a type of laser where the device’s active region contains a periodically structured element or diffraction grating. This structure provides optical feedback for the laser, ensuring that it operates on a single longitudinal mode, resulting in a narrow linewidth. The DFB laser diodes are known for their high wavelength stability and are widely used in applications requiring high spectral purity and stability.
