Paper Abstract

We present analytic formulas and numerical results for the resonance wavelength for cavity modes in a metallic nanoslit defined by its period (P), width (d), height (h) and the medium refractive indices (n) under the phase-matching conditions. The effective refractive inside the nanoslit cavity is numerically calculated and fit to an equation governed by the slit width and independent to the resonance peak wavelengths (λ). Three sensitivities defined by the change rate of the cavity-mode peak wavelength due to slit height, width and medium refractive index, respectively, are analyzed.
