In this research work, we show the successful inscription of fiber Bragg gratings into carbon-coated pure silica as well as germanium-doped glass fibers by applying the pulsed laser point-by-point manufacturing technique. First, the parameters used f

Fiber Bragg gratings are inscribed around the edge of a standard single mode fiber core by femtosecond laser technology. By analyzing the back reflected light intensities, a novel and precise 3D shape sensor is realized.

Femtosecond laser pulses are used to inscribe multiple evanescent coupling waveguides with Fiber Bragg gratings in the cladding of single mode fibers to create a fiberoptical 3D shape sensor in one production step. An evaluation and a sample applicat

A complex signalling network governs the response of Saccharomyces cerevisiae to an array of environmental stimuli and stresses. In the present article, we provide an overview of the main signalling system and discuss the mechanisms by which yeast in

Fiber Bragg grating based optical shape sensing is a new and promising approach to gather position and path information in environments where classical imaging systems fail. Especially a real-time in-vivo navigation of medical catheter or endoscope w

We present a fiber optical shape sensing system that allows to track the shape of a standard telecom fiber with fiber Bragg grating. The shape sensing information is combined with a medical visualization platform to visualize the shape sensing inform
Femtosecond laser pulses were used for the direct point-by-point inscription of waveguides into the cladding of standard single-mode fibers. Homogeneous S-shaped waveguides have been processed as a bundle of overlapping lines without damaging the sur

Fiber Bragg grating (FBG) technology is well known since more than three decades. It started in 1978 with the discovery of photosensitivity in optical fibers by Ken Hill et al. [1] when illuminating germanium-doped silica fibers with visible argon io
