Abstract: A new class of refractive index sensors using solid core photonic crystal fibres isdemonstrated. Coherent scattering at the cladding lattice is used to optically characterizematerials inserted into the fibre holes. The liquid to solid phase transition of water uponfreezing to ice 1h is characterized by determining the refractive index.
Keywords: optical fibre sensors; gratings; diffraction; photonic crystal fibres; microstructured fibres; capillary; ice.
