A series of perforated nano-hole structures on the gold film at different hole radius, hole depth of 100nm, and structural periodicity of 400nm were studied. It was found that transmission properties (i.e., intensity, FWHM, and resonance position) were strongly affected by hole radius and surrounding medium index of refraction. The maximum optical transmittance was observed as 31.9% in a nano-hole array of hole radius of 125nm and refractive index of 1.3. The maximum sensitivity of 300nm/RIU was obtained at index of refraction of 1.7, whereas the minimum one was calculated as 110nm/RIU in a nano-hole array of hole radius of 50nm. It was also found that on increasing the hole radius from 50 to 125nm, the spectral sensitivity was decreased, whereas the index sensitivity was increased on increasing the refractive index.
