Highly sensitive D shaped PCF sensor based on SPR for near IR

Abstract

A highly sensitive D shaped photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensor has been proposed. The use of Indium Tin Oxide as plasmonic metal helps in achieving SPR in near infrared region. The geometrical parameters of the proposed structure are similar to that of commercially available PCF which is widely available. Simulation results show that the proposed structure has a high wavelength sensitivity of 5200�nm/RIU with resolution of 1.92�נ10?5�RIU. � 2016, Springer Science+Business Media New York.
