Analytical and numerical electro-mechanical models are developed to predict the electrical resistance change due to fatigue damage in unidirectional fiber reinforced composite materials. Fatigue is attributed to underlying fatigue crack growth of pre-exist ...
The feasibility of integrating thermoplastic isotactic polypropylene/ montmorillonite nanocomposite matrices into conventional fiber-reinforced composites has been investigated. Two basic processing routes were considered: long glass fiber (GF)-reinforced ...
Polymer optical fibers (POF) have received increased attention in recent years in the fields of data communication and sensing applications. The lower cost and higher flexibility are the main advantages of POF compared to silica fibers and make them intere ...
Amplification through stimulated Brillouin scattering in optical fibers can totally modify the polarization properties of the light, enabling an all-optical polarization control and a direct estimate on the fiber birefringence. ...
We report on the demonstration of low-loss, single-mode GaN-InAlN ridge waveguides (WGs) at fiber-optics telecommunication wavelengths. The structure grown by metal-organic vapor phase epitaxy contains AlInN cladding layers lattice-matched to GaN. For slab ...
A method for seepage and settlement monitoring in earth embankment dams using fully distributed sensing along optical fibres is proposed. A model is developed for simulating and monitoring seepage and settlement systems. This model relates the strains and ...
The polarization properties of stimulated Brillouin scattering (SBS) amplification or attenuation in standard single-mode fibers are examined through vectorial analysis, simulation and experiment. Vector propagation equations for the signal wave, incorpora ...
Optical properties of multilayer InAs quantum dot waveguides, grown by molecular beam epitaxy, have been studied under applied electric field. Fabry-Perot measurements at 1515 nm on InAs/GaAs quantum dot structures yield a significantly enhanced linear ele ...
In this work, by using a comprehensive numerical model which rigorously describes the interaction between stimulated Raman scattering (SRS) and four-wave mixing (FWM), we verify that FWM processes, including depletion and parametric gain, generate a redist ...
The tedious and expensive process of attaching SIL contacts to the sensor edges may be advantageously replaced by soldering wires and cables directly to the sensor contact pads. However, this process is a bit more critical, as applying excessive heat can d ...
