Distributed Feed-Back; describing a laser with an etched grating close to its active zone, which acts as a filter, reducing overall gain for all but the wavelengths defined by the grating period. This technique allows to produce single-mode lasers also for pulsed mode operation.

Distributed feedback. A resonant-cavity laser using grids etched into the bottom of a semiconductor substrate as a reflective medium.
