Abstract

We report on highly reflective fiber Bragg gratings in photonic crystal fibers (PCF) that excite two types of cladding mode resonances. We consider two hexagonal lattice PCF structures with a similar air-filling fraction (0.4) but different lattice pitch values (2.5 and 3.6 μm). We demonstrate both experimentally and numerically that the lattice parameters of the microstructure influence the spectral location of the resonances and the spectral span that they occupy. For the PCF with the lattice pitch of 2.5 μm, we demonstrate its application for surface plasmon-enhanced refractometry of waterbased solutions with potential for biosensing applications.
