About us

FBGS is a Germany / Belgium based developer and manufacturer of high strength Fiber Bragg Gratings (FBGs), Interrogators, Sensors and custom-made fiber optic sensing solutions. Therefore, FBGS has developed two unique and fully automated production processes for FBGs which result in very high quality and cost-effective sensing components with unique optical and mechanical characteristics.

FBGS’s products are suitable for both standard and bespoke applications in industries such as: medical, composite, transport, process, civil & geo, telecom and R&D. FBGS supplies ‘Draw Tower Gratings’ – DTG® and ‘FemtoSecond Gratings’ – FSG® as an OEM component and our products can today be found in many applications and products developed by our customers worldwide.

Products and services

FBGS offers high strength Fiber Bragg Gratings (FBGs), Interrogators, Sensors and custom-made fiber optic sensing solutions.The growing interconnectability of people, devices and machines has led to a rapidly increasing need for sensing solutions allowing to measure a variety of parameters in a broad range of applications. Optical fibers are light weight, passive and unobtrusive sensing wires with a thickness comparable to a human hair. Sensing features can be tailored to the needs of the application and the unprecedented multiplexing capabilities allows to move away from traditional discrete measurement points to continuous measurements visualizing strain and temperature gradients, pressure, multi-directional force, curvature and shape information. The technology is today being used in various industries ranging from industrial processing, structural health monitoring and energy to aerospace, medical and safety & security.

Draw Tower Gratings

We offer three types of DTG® with unique characteristics compared to classically produced FBGs, such as extremely high breaking-strength, spliceless array configuration and uniform coating coverage. FBG parameters and coating material can be selected based on customer needs.

News & Innovations

Blood flow monitoring with fiber optic sensors
A tiny fiber-optic sensor has the potential to save lives in open heart surgery, and even during surgery on pre-term babies. The new micro-medical device could surpass traditional methods used to monitor blood flow through the aorta during prolonged and often dangerous intensive care and surgical procedures - even in the tiniest of patients. The continuous cardiac flow monitoring probe, under development at Flinders University, is a safe way to give a real-time measurement of blood flow. "The minimally invasive device is suitable for neonates right through to adults," says research leader Strategic Professor John Arkwright, an expert in using fiber-optic technologies in medical diagnostics. Professor Arkwright says the device has the potential to be a game-changer - particularly for very young babies, which are particularly susceptible to sudden drops in blood pressure and oxygen delivery to their vital organs.

Design and manufacturing of a 2-DOF force sensing needle for retinal surgery
Among the global researchers, the Mechanical Engineering group at University of Leuven, in concert with the University Hospital Leuven, are on a deliberate mission to explore an in-vivo 2-DOF smart sensing technique associated with robotic-assisted ophthalmic surgical procedures. The success of this technique comes as a result of the development of a DTG®-based sensing modality that boosts the performance of the delicate surgical tools utilized in recanalization of retinal vein occlusion (RVO) affecting over 16 Million people worldwide.

Pressure Sensing: Fiber Bragg Gratings used to ‘shed light’ on human digestion
Prof. John Arkwright and his team at CSIRO in Sydney Australia have developed a unique fiber optic catheter including FBGS sensing fiber that allows gastroenterologists to see and understand the intricate workings of the human digestive system. The device uses arrays of Fiber Bragg Gratings to measure variations in pressure at 10 mm intervals along the catheter scan to enable observation of the complex muscular contractions that transport food through the deep recesses of our large bowel. The device is now being prepared for regulatory approval by CSIRO licensees of the technology. The turning point in product development occurred when Prof. Arkwright started to use DTG arrays to form the catheters pressure sensors. “The dramatic improvement in the tensile strength of the DTG arrays simplified the catheter assembly and also made the device strong enough to withstand real-life clinical use.” said Prof. John Arkwright.
