    A DFB laser is a laser diode or optical fiber laser with a low linewidth grating that extends throughout the cavity rather than simply at the opposite edges. Because they are single-frequency laser diodes, distributed feedback lasers have short linewidth and effective side modes.

    Distributed feedback (DFB) laser diodes feature a grating structure within the semiconductor and thus operate in both longitudinal and transverse single mode. Tuning is achieved by modulating either the laser current or the chip temperature.
