Název v původním jazyce

Theoretical analysis of a fiber optic surface plasmon resonance sensor utilizing a Bragg grating

Popis výsledku v původním jazyce

A rigorous theoretical analysis of a fiber optic surface plasmon resonance sensor is presented. The sensor is based on the spectroscopy of mixed surface plasmon-fiber cladding modes excited by the fundamental mode of an optical fiber via a Bragg gratingformed in the fiber core. The transmission spectrum is calculated by means of the Coupled Mode Theory. The modal structure is theoretically analyzed using a 3-D method based on a field expansion approach for matching the field continuity at the boundaryof the layers. The theoretical analysis revealed a series of narrow transmission dips associated with the coupling of the fundamental mode to the mixed surface plasmon-fiber cladding modes. The sensitivity of these dips to changes in the refractive indexof the analyte is calculated. Moreover, the refractive index resolution of the sensor was estimated to be better than 2 x 10(-6) RIU.
