Abstract :
A highly integrated sensor based on the hybrid coupling between short range surface plasmon polariton (SRSPP) and dielectric waveguide mode is proposed for ultra-thin analytic layer detection. For an analytic layer thinner than 1/10 wavelength, the refractive index resolution can be as high as 5.5×10-6.
