Abstract

In this work, we design and numerically analyze a D-shaped photonic crystal fiber (PCF) plasmonic sensor based on metallic grating. The influence of the geometrical and optical parameters of the metallic grating on the performance of the proposed plasmonic refractive index sensor are thoroughly investigated considering several metals and grating configurations. The metallic grating is placed over the polished surface and gold and silver are used for this purpose. The sensitivity of the sensor and the resonant wavelength can be tuned by judiciously adjusting the grating parameters: shape, thickness, width and period. The proposed sensor exhibits excellent sensing characteristics and can be applied for several real time and fast response applications such as biological, biochemical and environmental sensing..
