distributed feedback laser

A type of diode laser that uses diffraction gratings rather than mirrors to create the resonance and oscillation in the cavity. It produces a finer range of wavelengths than a Fabry- Perot cavity. A distributed Bragg reflection laser is a similar technology that uses Bragg gratings. The other major type of laser uses a Fabry-Perot cavity with mirrors. See Fabry-Perot and fiber Bragg grating.

The laser approach is also suitable for multiplexing since the laser power is on the order of 150 mW and can be divided into several fibers with a separate modulator for each fiber.|8~ The alternative direct laser diode transmission systems, typically based on distributed feedback laser diodes, are limited in output power for the same level of noise performance, which is typically restricted to a few milliwatts.
