The performance of a metal-clad planar waveguide-based sensor coupled with a liquid-filled prism is studied and is compared with a similar waveguide sensor coupled with a solid prism. The characteristic equations of these waveguides are obtained by matching field components at various boundaries, and the reflectivity of these waveguides is obtained using transfer matrix method. The obtained dispersion...
Surface plasmon resonance (SPR) based tapered fiber optic sensor having nanostructure film with different particle sizes and volume fractions are analyzed and compared. Using ray-tracing model change in resonance wavelength, propagation length and penetration depth in metal of coupled light are obtained for proposed sensor configuration. The sensitivity of the sensor has been estimated with volume...
