The project is aimed at joint study of a novel optical fibre sensor for environmental and/or bichemical sensing. The novel feature of the sensor relies on the application of a Bragg grating in the fibre sensor based on resonant excitation of the surfaceplasmon (SPR) at the metal-dielectric boundary. SPR optical fibre sensors make it possible to considerably reduce the volume of the sensed medium without reducing the sensitivity of the sensor and to miniaturize the sensor. The task of the reseach project is to investigate the potential of a combination of the SPR fibre sensor with a Bragg grating created inside the excitation region of SP wave in the optical fibre. It is envisaged that this combination could help further enhance the properties of the SPR waveguide sensor and open space for new applications.
