Distributed-feedback laser
A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating.

Distributed Feedback Lasers
Good-quality long-distance optical transmission over fiber needs lasers which emit at a single wavelength. This is almost universally realized by putting a wavelength-dependent reflector into the
High-power eight-wavelength distributed feedback laser array with 100
We propose and experimentally demonstrate a high-power eight-wavelength distributed feedback (DFB) laser array with 100 GHz spacing using the grating reflector (GR). The GR, which is

9.6.2 Distributed Feedback Lasers Applications such as high-speed data transmission in fiber optics require limiting laser emission to a narrower range of wavelengths than possible with a Fabry Perot
Distributed-Feedback Lasers
Wavelength Selectability • Compared with Fabry-Perot lasers, DFB or DBR laser is easy to achieve single-longitudinal-mode operation because the spacing between the m-th and the (m±1)-th mode is
Distributed-Feedback Lasers | Springer Nature Link
Distributed feedback lasers offer improved wavelength stability as compared to cleaved-end-face lasers, because the grating tends to lock the laser to a given wavelength.
Distributed-feedback (DFB) Laser Coherence and Linewidth
Distributed-feedback (DFB) semiconductor lasers are single-mode devices operating at 1550 run. There are favourable properties at this wavelength including low fibre attenuation, applicability of dense
