- Theoretical Study of Surface Plasmon Resonance-based Fiber Optic Sensor Utilizing Cobalt and Nickel Films Sarika Shukla Navneet K. Sharma Vivek Sajal Física, Astronomía y Matemáticas Sensor Cobalt Nickel Optical fiber Surface plasmon resonance t A surface plasmon resonance (SPR) based fiber optic sensor with cobalt (Co) and nickel (Ni) layers (one layer at a time) is theoretically analyzed. The sensitivity of sensor increases linearly with increase in refractive index of sensing medium for all thicknesses of Co and Ni layers. Besides it, SPR sensor with Co layer has been shown to demonstrate higher sensitivity than that of Ni layer. The usage of Co in place of noble metals (such as gold and silver) curtails the cost of SPR sensor. Optimized thicknesses of Co and Ni layers are found to be 80 nm and 60 nm, respectively. 2016 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46445584007 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3 Vol.46
