50th Anniversary of DFB Lasers: What Future Developments Can We Expect for Semiconductor Lasers?

50th Anniversary of DFB Lasers: What Future Developments Can We Expect for Semiconductor Lasers?

The Distributed Feedback Laser (DFB Laser) is a type of semiconductor laser known for its high single-mode performance. Its core feature is the introduction of a periodic refractive index modulation structure (i.e., a Bragg grating) within the laser, which enables optical feedback and wavelength selection, resulting in the output of a single wavelength laser. DFB … Read more
