Explore: Distributed Feedback Lasers

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

extended-cavity diode lasers and volume Bragg grating lasers, but these are not properly called DBR lasers. A distributed-feedback laser (DFB) is a type of

in contrast to Fabry–Pérot cavities and distributed feedback lasers, neither reflective surfaces nor distributed periodic structures are used in RLs, as

hybrid materials used as laser matrices. Other types of solid-state organic lasers include the organic semiconductor lasers that use conjugated polymers

Quantum-cascade lasers (QCLs) are semiconductor lasers that emit in the mid- to far-infrared portion of the electromagnetic spectrum and were first demonstrated

as gain media for a fiber laser.[citation needed] An advantage of fiber lasers over other types of lasers is that the laser light is both generated and

dye lasers were demonstrated with the introduction of distributed feedback laser designs in 1999 and distributed feedback waveguides in 2002. Laser linewidth
