CartDistributed Feedback (DFB) Lasers
Distributed Feedback (DFB) Laser Diodes are single-frequency and offer a Narrow Linewidth with good side mode suppression ratio (SMSR). They utilize a Bragg grating to ensure single-frequency emission.
Discreet-Mode (DM) Laser Diodes offer very similar performance to DFB Lasers. Discreet-Mode Laser Diodes are produced with a simple and low-cost fabrication process and have many advantages. For example, they have very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.
Additionally, check out this article, titled “Laser Diodes for Gas Sensing: Mode-Hop-Free Tunability with High SMSR” for some more in-depth reading about the DFB-like ‘Discreet-Mode’ laser diodes.
Our Products
Free-space and fiber pigtailed versions are available in these NIR, SWIR, & LWIR (from ≈1260nm to 16µm) narrow linewidth lasers, with up to 50mW output. Furthermore, packages include HHL, TO-Can, and fiber-coupled butterfly options. Finally, we offer a wide range of wavelengths and output powers to choose from in our DFB Lasers.
