Why Choose Customized DFB Lasers for Your Optical Component Needs?

Understanding DFB Lasers

What are DFB Lasers?

Distributed Feedback (DFB) lasers are a type of semiconductor laser characterized by their ability to provide stable and coherent light output. The name "distributed feedback" refers to a unique structure in which a periodic refractive index grating is integrated into the laser’s active medium. This structure allows for the selective amplification of certain wavelengths of light, making DFB lasers ideal for numerous applications in telecommunications, sensing, and medical devices.

The Unique Structure and Functionality of DFB Lasers

The core advantage of DFB lasers lies in their design. The periodic grating serves as a filter, allowing specific wavelengths to resonate while suppressing others. This results in a narrow linewidth, minimal noise, and high output power, which are crucial for applications requiring precision and reliability.
