“…This means that the losses are negligible when the fiber is bent with a radius above 25 mm. The tensile strength and the Young's modulus are 70N and 2.7GPa [20], [26], respectively. These characteristics provide good mechanical properties at the time of manufacturing the sensor and permit to bend the fiber below the minimum bend radius without break, despite of the attenuation increments.…”

Abstract:The design and development of a plastic optical fiber macrobend temperature sensor is presented. The sensor can op-erate in a temperature range from −55 to 70 °C and has a linear response versus temperature with a sensitivity of 8.95·10−4 °C−1. The sensor system uses the ratio of transmittance at two wave-lengths to implement a selfreferencing technique in order to avoid undesirable power fluctuations influence. The transmittance ratio precision is 0.1%. An analysis has been developed to find the two wavelengths which ratio offers the highest linearity and sensitiv-ity response. Experimental results are successfully compared with theoretical approaches.

Waveguides made of poly-methyl-methacrylate (PMMA) play a major role in the homogeneous distribution of display backlights as a matrix for solid-state dye lasers and polymer optical fibers (POFs). PMMA is favored because of its transparency in the visible spectrum, low price, and well-controlled processability. Nevertheless, technical drawbacks, such as its limited temperature stability, call for new materials. In this work, the copolymerization technique is used to modify the properties of the corresponding homopolymers. The analytical investigation of fourteen copolymers made of methyl-methacrylate (MMA) or ethyl-methacrylate (EMA) as the basis monomer is summarized. Their polymerization behaviors are examined by NMR spectroscopy with subsequent copolymerization parameter evaluation according to Fineman-Ross and Kelen-Tüdös. Therefore, some r-parameter sets are shown to be capable of copolymerizations with very high conversions. The first applications as high-temperature resistant (HT) materials for HT-POFs are presented. Copolymers containing isobornyl-methacrylate (IBMA) as the comonomer are well-suited for this demanding application.

“…The visco-elastic nature of POF can lead to problems at higher strains 11 , nevertheless hysteresis free behaviour at strains of over 10% have been reported 12 . There are other properties of POF that can also be used to advantage in sensor systems.…”

Polymer photonic crystal fibres combine two relatively recent developments in fibre technology. On the one hand, polymer optical fibre has very different physical and chemical properties to silica. In particular, polymer fibre has a much smaller Young's modulus than silica, can survive higher strains, is amenable to organic chemical processing and, depending on the constituent polymer, may absorb water. All of these features can be utilised to extend the range of applications of optical fibre sensors. On the other hand, the photonic crystal -or microstructured -geometry also offers advantages: flexibility in the fibre design including control of the dispersion properties of core and cladding modes, the possibility of introducing minute quantities of analyte directly into the electric field of the guided light and enhanced pressure sensitivity. When brought together these two technologies provide interesting possibilities for fibre sensors, particularly when combined with fibre Bragg or long period gratings. This paper discusses the features of polymer photonic crystal fibre relevant to sensing and provides examples of the applications demonstrated to date.
