About us
engionic Femto Gratings – Pioneering Fiber Bragg Grating Technology
engionic Femto Gratings GmbH is the world's first commercial supplier of femtosecond-laser-written Fiber Bragg Gratings (FBGs), enabling advanced sensing solutions for a wide range of industrial, medical and high-performance applications.
Our innovative femtosecond-laser technology sets new standards in FBG manufacturing. Unlike conventional inscription methods, it enables gratings to be written into virtually any optically transparent fiber material, including specialty fibers, without requiring germanium doping. The process operates directly through various fiber coatings, eliminating the need for stripping and recoating while preserving superior mechanical strength.
This technological flexibility allows us to manufacture FBGs with an exceptionally broad range of specifications, including highly specialized gratings for harsh environments, high-temperature applications and dense sensor arrays with thousands of sensing points.
Combining advanced laser technology with highly automated manufacturing, we deliver exceptional precision, consistent quality and cost efficiency. Our scalable production capabilities range from individually customized FBGs and prototypes to high-volume serial production, with short lead times and outstanding flexibility.
engionic Group – Integrated Fiber Optic Expertise
As part of the engionic Group, we combine pioneering FBG technology with more than three decades of expertise in fiber optics, precision engineering and sensor manufacturing.
Our unique, fully integrated in-house value chain covers every stage of fiber optic sensor production – from FBG inscription and precision CNC machining to sensor assembly, calibration, protective housings and complete sensing systems.
This comprehensive expertise enables us to provide tailored, reliable and cost-effective solutions from a single source, supporting our customers from initial development and prototyping through to industrial-scale production.
From a single Fiber Bragg Grating to a complete sensing solution – precision, innovation and manufacturing excellence from one source.
