Rapid and reliable communication technologies are becoming increasingly necessary. Since the world is rapidly transitioning to digital platforms, there is an increased demand for communication tools and solutions. This has resulted in the development of communication systems that are quick, sophisticated, and reliable. However, the development of these systems is heavily reliant on their components, such as DFB lasers. A DFB laser is a type of diode laser that uses diffraction gratings rather than mirrors to produce resonance and oscillation in the cavity. The goal of a distributed feedback (DFB) laser is to sharpen the output of traditional Fabry-Perot lasers.
