AbstractPhotonic analogues of the relativistic Kronig-Penney model and of relativistic surface Tamm states are proposed for light propagation in fibre Bragg gratings (FBGs) with phase defects. A periodic sequence of phase slips in the FBG realizes the relativistic Kronig-Penney model, the band structure of which being mapped into the spectral response of the FBG. For the semi-infinite FBG Tamm surface states can appear and can be visualized as narrow resonance peaks in the transmission spectrum of the grating.

Dual Measurement

Fibre optic sensing devices have been produced for the dual measurement of strain and temperature using the combined properties of fibre Bragg gratings and the fluorescence lifetime of erbium-doped fibre. Two different sensors were constructed with the fibre Bragg grating written in normal fibre and also written directly in the Er3+-doped fibre. Results obtained indicate that this technique can be used to measure strains and temperatures with accuracies of approximately 1.2°C and 20.4 με
