Specifically, the influence of an infiltration method on the LC molecular alignment inside fibre air-channels and, thus, on light guidance is discussed. Switching between propagation mechanisms, namely the transition from modified total internal reflection (mTIR) to the photonic bandgap effect obtained by varying external temperature is also demonstrated.}, type={Article}, title={Light propagation mechanism switching in a liquid crystal infiltrated microstructured polymer optical fibre}, URL={http://www.journals.pan.pl/Content/116147/PDF-MASTER/pan_doi_blank.pdf}, keywords={photonic crystal fibres, liquid crystals, microstructured polymer optical fibres, photonic bandgap, photonic liquid crystal fibres}, }
