Polarization-Maintaining Fibers are a specialized type of singlemode fiber designed to maintain the polarization of light as it travels through the fiber. These fibers incorporate stress elements within the cladding, which apply mechanical stress to the fiber core, inducing birefringence. This unique design ensures that the polarization of the transmitted light remains consistent, making them essential for applications requiring high precision and stability.

The stress elements embedded in the cladding of these fibers can be crafted in various designs, such as the Panda and Bow Tie configurations. These designs are integral to the fiber's ability to maintain polarization, as they directly influence the mechanical stresses applied to the core. The fibers are primarily utilized in optical networks, pump lasers, and microscopic applications, where maintaining the polarization state is crucial for performance.

Polarization-maintaining fibers are available in a range of specifications to suit different wavelength requirements. They are designed to operate efficiently across various wavelength ranges, from visible to infrared (VIS-IR), providing flexibility for diverse applications. The fibers feature a consistent jacket diameter, typically around 125 µm, and are coated with acrylate for durability and protection. Additionally, custom jacketings and assemblies can be requested to meet specific application needs.

With a focus on precision and reliability, these fibers offer low attenuation rates and consistent performance across their specified wavelength ranges. They are available in multiple configurations, each tailored to specific wavelength and mode field diameter requirements. This adaptability ensures that users can find the perfect fiber solution to maintain polarization in their optical systems, enhancing the overall efficiency and accuracy of their applications.
