About us

FiSens develops, manufactures, and markets accurate fiber optic sensor solutions based on fiber Bragg grating (FBG) sensor arrays and fiber-integrated spectrometers. We produce optical fibers with high sensing and multiplexing capabilities on the smallest possible footprint. Our technology maintains mechanical and signal integrity despite being utilized in harsh environments.

For more than 10 years we have been developing fully automated manufacturing processes for high-volume production of our products. FiSens has an annual production capacity of up to 2 million FBG sensors. Our FBG sensors are precise, reliable and of highest quality. They are electromagnetically immune, safe in explosive, high radiation, highly corrosive, or high-temperature environments, and are engineered for countless different applications.

FiSens offers a worldwide unique fully integrated solution including both FBG sensor and FBG Interrogator. Together they can be directly used to record spatial profiles of temperatures and strains. Visit our booth and learn more about our technology.

Products & Services

We specialize in the development, manufacturing, and promotion of cutting-edge fiber optic sensor systems. Our expertise lies in leveraging our proprietary femtosecond laser process to fully automate the production of Fiber Bragg Gratings (FBGs) and a unique FiSens Diffraction Grating directly within the core of standard telecom fibers. These two integral components form a seamlessly integrated, cost-effective sensing system that empowers our clients to monitor a wide range of variables, including temperature, strain, and force at any desired point along the fiber.

Remarkably slender, with a thickness comparable to human hair, like an artificial nerve, FiSens sensing fibers can be effortlessly incorporated into a myriad of objects. This attribute equips them with the ability to perceive their surroundings effectively.

The 850nm Sensor Array with silica capillary

FBG Sensor Array 1550nm

Our Ultra-high strength (UHS) FBGs combine the best possible specifications for FBG sensors at 1550nm. In addition to their ultimate strain limit of typically 5-6%, they exhibit virtually no transmission loss, enabling the production of medium reflectivity FBG arrays with quantities over 2,000 pieces. Additionally, they exhibit the lowest polarization dependency and a very high side lobe suppression.
