Paper Abstract

Fiber optic surface plasmon resonance sensor structure with double clad and subwavelength metallic grating is proposed. The sensing characteristics of the proposed sensor structure are numerically analyzed with a combination of geometric optics method and rigorous electromagnetic analysis method (rigorous coupled wave analysis). The analysis shows that, in the proposed sensor structure, two resonance dips appear clearly. One has narrower bandwidth and the other has higher sensitivity at resonance point shifted toward longer wavelength region in the transmission spectrum than the conventional surface plasmon resonance sensor structure with flat dielectric/metal interface.
