We also present experimental results for both backward and forward fluorescence recapturing within a MOF as a function of fiber length and demonstrate a good qualitative agreement between the numerical model and experimental results. We demonstrate higher efficiency of fluorescence recapturing into backward modes in comparison with that of forward modes.enCopyright © 2008 Optical Society of AmericaSpectrometry, FluorescenceSensitivity and SpecificityReproducibility of ResultsEquipment DesignEquipment Failure AnalysisFiber Optic TechnologyOptical FibersEnhanced fluorescence sensing using microstructured optical fibers: a comparison of forward and backward collection modesJournal article00200819682008100714352010.1364/OL.33.0014730002580178000272-s2.0-4754910311542440Warren-Smith, S.
