PM, polarizing & spun Fibers

Precision and control have become paramount in the evolving field of sensing technologies. Meeting the demands of sophisticated applications, from ultra-precise fiber-optic gyroscope systems to cutting-edge quantum and cold-atom applications, Exail pioneers the development of specialized fibers that offer unparalleled efficiency, precision, and stability.

Polarizing specialty fiber for unrivalled precision

At the heart of these advancements is Exail's Polarizing Maintaining (PM) specialty fiber, a technological breakthrough designed to address the challenges posed by intricate sensing requirements. Boasting high birefringence to maintain stable linear polarization, coupled with Exail's meticulously optimized PM fiber coating, this fiber achieves the world's highest performance levels. This innovative solution sets a new standard for precision, ensuring optimal performance in diverse sensing applications.

PM Gyro Fibers

Powering high-performance navigation systems, Exail's PM Gyro fibers exemplify high consistency, accuracy, and international qualification. Engineered to enhance the precision of fiber-optic gyroscopes, these fibers guarantee reliability across a spectrum of applications—from terrestrial operations to space exploration. Their high consistency and meticulous end-to-end control of optical properties confer a distinctive advantage by minimizing signal artifacts generated by the fiber.

PM Coils

In a fiber-optic gyroscope, the quality and consistent performance of the fiber coils are crucial for overall accuracy. Tailored to specific requirements.

Spun Fibers

Exail's Spun Polarization Maintaining Optical Fibers, designed for 1310 and 1550 nm applications, ensure circular polarization preservation with minimized thermal and vibrational dependencies. Ideal for high-sensitivity Fiber-Optic Current Sensors (FOCS), these fibers offer exceptional sensitivity, and
rapid response time. Proprietary innovative elliptical core design drastically reduces the temperature dependence of FOCS sensors.

PM Fiber Current Sensors

Exail PM Fibers Current Sensors feature advanced polarization maintaining fibers designed specifically for Fiber-Optic Current Sensors (FOCS).
Matched with Exail’s Spun fibers, these are the ideal fiber to build your delay lines, feeder lines to measurement unit or modulation component, as well as quarter wave plates.

Polarizing Fibers

Exail's Polarizing (PZ) fiber, featuring a specialized waveguide design and optimized glass composition, swiftly eliminates any polarization state other than the guided one. With a broad polarizing window, low attenuation, and high extinction ratio (≥ 30 dB) across different wavelengths, PZ fibers excel in applications such as quantum optics, cold atoms, all-fiber polarizers, fiber optic current sensors, and gyros. Exail also provides ready-to-use polarizing solutions based on PZ fibers.

Standard PM Fibers

Exail offers a selection of standard PM Fibers from 350 to 2300 nm with a 125 µm cladding diameter, providing high birefringence, excellent polarization maintaining properties, low attenuation, and low solarization. Customized coatings and wavelengths are also available upon request. These fibers find applications in coherent beam delivery, delay lines, diode and modulator pigtails, fiber optic sensors, gyroscopes, instrumentation, Lyot depolarizers, and polarization-sensitive components.
