− This article deals with the technical properties of fiber Bragg gratings with regard to their use as the strain-sensitive element in force transducers. Electrical strain gages are widely used in modern, precise force transducers. The electrical strain gage provides both outstanding technical properties and cost-effectiveness. Besides the electrical strain gage, the measurement principle of fi...

Optical solitons with ber Bragg gratings and polynomial law of nonlinear refractive index are addressed in the paper. The auxiliary equation approach together an addendum to Kudryashov's method identify soliton solutions model. Singular periodic emerge from these integration schemes as a byproduct. Keywords: solitons; cubic-quartic; gratings.

Abstract: Phase masks are important optical elements that have been utilized for several decades in a large variety of applications. Recently, we demonstrated a new type of phase masks fabricated by encoding phase profiles into volume Bragg gratings, allowing these holographic elements to be used as phase masks at any wavelength capable of satisfying the Bragg condition of the hologram. Here, w...

We report on an optical technique for measuring thermal expansion and magnetostriction at cryogenic temperatures and under applied hydrostatic pressures of 2.0 GPa. Optical fiber Bragg gratings inside a clamp-type pressure chamber are used to measure the strain in a millimeter-sized sample of CeRhIn₅. We describe the simultaneous measurement of two Bragg gratings in a single optical fiber using...

Impact detection in aeronautical structures allows predicting their future reliability and performance. An impact can produce microscopic fissures that could evolve into fractures or even the total collapse of the structure, so it is important to know the location and severity of each impact. For this purpose, optical fibers with Bragg gratings are used to analyze each impact and the vibrations...

Die sensorische Grundlage für den taktilen Sensor sind die soge-nannten Fiber Bragg Gratings. Dies sind in Lichtwellenleitern bzw.

Recent advances in the development of two-dimensional holographic Bragg reflectors in planar lightwave circuits have demonstrated the feasibility of highly customizable multi-wavelength filters based on photonics nanostructures programmable to recognize spectra with up to 2000 spectral lines. Such filters rival or exceed performance of free space gratings, thin film filters and Bragg gratings a...
