In the present study, metamaterial based optical sensor is proposed and optimization of the proposed optical sensor for sucrose detection is done. In this paper single negative metamaterial surface is fabricated using E-beam lithography technique to be used as an optical sensor for broad wavelength range using UV–Vis–NIR spectrometer. The resultant sensitivity and detection accuracy of the proposed metamaterial based sensor is higher than simple thin film sensor, i.e. 1740.8 (nm/RIU) and 0.893 respectively. The center wavelength of the proposed optical sensor is 967 and 933 nm for gold and metamaterial based-sensor respectively, which ensures the larger bandwidth available in the case of metamaterial based-sensor. It is observed that high surface to volume ratio of metamaterial surface ensures the better sensitivity of the proposed sensor. Simple structure of presented metamaterial surface also makes sure reliable and precise fabrication of metamaterial surface.
