COC-PPBGs can be handled and fabricated efficiently by employing a single writing step procedure which features simultaneous generation of waveguide and Bragg grating structure within an injection molded substrate. The resulting photonic structures exhibit an attenuation as low as 1.2 dB cm-1 and a reflectivity up to 99 \%. The potential of COC-PPBGs for high-temperature applications is proven by demonstrating temperature measurements up to 160 °C. Moreover, it is possible to employ single PPBGs for multidimensional stress and strain sensing or even three-dimensional shape reconstruction. Due to their excellent properties, it is feasible to integrate COC-PPBGs into commercial-grade carbon fiber reinforced polymer workpieces for structural health monitoring. Furthermore, utilization of appropriate coatings enables functionalization of PPBGs for refractive index sensing and thus biochemical applications. Beside the fabrication and characterization of COC-based PPBGs, this contribution exemplifies and reviews such applications.}, subject = {Optischer Sensor}, language = {en} } @article{BelleScheurichHellmannetal.2010, author = {Belle, Stefan and Scheurich, Steffen and Hellmann, Ralf and So, Sik and Sparrow, Ian and Emmerson, Greg}, title = {Refractive index sensing for online monitoring water and ethanol contents in biofuels}, series = {Sensors}, journal = {Sensors}, number = {7726}, issn = {1424-8220}, doi = {10.1117/12.853849}, year = {2010}, subject = {Biokraftstoff}, language = {en} } @inproceedings{RosenbergerBelleHellmann2011, author = {Rosenberger, Markus and Belle, Stefan and Hellmann, Ralf}, title = {Detection of unlabeled DNA hybridization with a planar Bragg Grating Sensor}, series = {XXV International MicroCAD Conference - Sensing Technologies, Miskolc (Hungary)}, booktitle = {XXV International MicroCAD Conference - Sensing Technologies, Miskolc (Hungary)}, number = {Section R}, pages = {67 -- 72}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @inproceedings{RosenbergerBelleHellmann2011, author = {Rosenberger, Manuel and Belle, Stefan and Hellmann, Ralf}, title = {Optical interrogation of chemical and temperature bragg grating sensors using tunable fiber coupled bandpass filter}, series = {Proceeding XXV microCAD, International scientific conference, 2011, Section H}, booktitle = {Proceeding XXV microCAD, International scientific conference, 2011, Section H}, pages = {25 -- 30}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @inproceedings{BelleRosenbergerHellmann2011, author = {Belle, Stefan and Rosenberger, Manuel and Hellmann, Ralf}, title = {Optical fibre sensing in the production process and storage of biofuels}, series = {Proceeding XXV microCAD, International scientific conference, 2011, Section A}, booktitle = {Proceeding XXV microCAD, International scientific conference, 2011, Section A}, pages = {21 -- 26}, year = {2011}, subject = {Biokraftstoff}, language = {en} } @article{BelleRosenbergerHellmann2011, author = {Belle, Stefan and Rosenberger, Manuel and Hellmann, Ralf}, title = {Evanescent wave planar bragg grating sensor for real-time detection of unlabelled biomolecules}, series = {Optics Express}, journal = {Optics Express}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @article{GirschikofskyRosenbergerBelleetal.2011, author = {Girschikofsky, Maiko and Rosenberger, Manuel and Belle, Stefan and Brutschy, Malte and Waldvogel, Siegfried and Hellmann, Ralf}, title = {Optical planar bragg grating sensor for real-time detection of benzene, toluene und xylene in solvent vapour}, series = {Sensors \& Actuators, B - Chemical}, volume = {171/172}, journal = {Sensors \& Actuators, B - Chemical}, number = {8/9}, pages = {338 -- 342}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @article{GirschikofskyRosenbergerBelleetal.2011, author = {Girschikofsky, Maiko and Rosenberger, Manuel and Belle, Stefan and Brutschy, Malte and Waldvogel, Siegfried and Hellmann, Ralf}, title = {Highly sensitive detection of naphthalene in solvent vapor using a functionalized PBG refractive index sensor}, series = {Sensors}, volume = {12}, journal = {Sensors}, number = {2}, doi = {10.3390/s120202018}, pages = {2018 -- 2025}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @inproceedings{RosenbergerBelleHellmann2011, author = {Rosenberger, Manuel and Belle, Stefan and Hellmann, Ralf}, title = {Detection of biochemical reaction and DNA hybridization using a planar bragg grating sensor}, series = {Proceeding SPIE, Vol. 8073, article id: 80730C}, booktitle = {Proceeding SPIE, Vol. 8073, article id: 80730C}, number = {8073}, doi = {10.1117/12.886785}, year = {2011}, subject = {Bragg-Reflektor}, language = {en} } @inproceedings{RosenbergerBelleHellmann2009, author = {Rosenberger, Manuel and Belle, Stefan and Hellmann, Ralf}, title = {Optical interrogation of bragg grating sensors using tunable fibre based bandpass filter}, series = {Proceedings of the 20st international science conference, Mittweida}, booktitle = {Proceedings of the 20st international science conference, Mittweida}, year = {2009}, subject = {Bragg-Reflektor}, language = {en} }
