This distributed feedback lasers buying guide provides technical background, comparison of major types, selection criteria, and an overview of suppliers.
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
Thorlabs'' Distributed Feedback (DFB) Lasers are narrow-linewidth, single-frequency laser diodes that use a corrugated waveguide throughout the active region of the
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.
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.
