A Distributed-feedback (DFB) laser is a semiconductor source of coherent light, whose active region includes periodic changes in the effective refractive index along the cavity.
This wavelength is determined by the grating''s period. Conventional DFB lasers have a single mode wavelength from 1.3 to 1.55 µm. This picture shows exactly how a DFB laser works.
These DFB lasers are designed for mode-hop-free, continuous current tuning from 15 °C to 35 °C. These diodes can be both temperature and current tuned to achieve the desired operating
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.
