Physical and technical limits become important when trying to increase data transfer rates to tens of gigabits and higher for already installed optical cables. Polarization-mode dispersion (PMD) is one of the crucial transmission constraints, especia

A sensor for accurate and long-term fluid pressure monitoring in oil bore-holes based on optical fiber Bragg gratings (FBGs) is presented. The sensor converts fluid pressure into optical fiber strain by means of a mechanical transducer designed to wi

Fiber optical sensors based on Bragg gratings were used to monitor the strain in suspension or prestressing CFRP (carbon fiber reinforced polymer) cables in bridges. The sensors were either adhered to the surface of the CFRP wires for the suspension

We have demonstrated that output grating couplers on thin SiO2-TiO2 waveguides are sensors which respond (i) with sub-monomolecular sensitivity to the adsorption of molecules out of a gaseous or liquid sample covering the waveguide in the grating reg

With an input grating coupler sensor, we investigated the immunobinding of an antibody (rabbit anti-h-IgG) to the antigen human immunoglobulin G (h-IgG), immobilized by adsorption on a SiO2-TiO2 waveguide surface. The feasibility of direct immunosens
