distributed feedback laser
- A type of semiconductor laser which employs feedback to make certain modes in the resonator oscillate more than others. To do so, the grating spacing is arranged so that the feedback is distributed in both directions, which creates a condition that can approach single-mode oscillation. Its abbreviation is DFB laser. Also called distributed Bragg reflector laser.
