      In this study, we have proposed photonic crystal fiber based surface plasmon resonance sensor, where hexagonally arranged circular air holes surrounded the core of photonic crystal fiber. Gold has been placed on top surface as a metallic layer, while all the structure covered with analyte channel. Full Vectorial Finite Elimination Method has been used for analysing effective refractive index and confinement losses for proposed sensor. When refractive index of analyte channel changes, spectral interrogation and amplitude methods have been used for calculating the sensitivities and resolutions of offered sensor.

      In this study, the relative sensitivity coefficient of the proposed hexagonal shaped photonic crystal fiber (PCF) has been investigated by employing the full vectorial finite element method (FEM). Propagation loss of the three different liquid analyte with 35 elliptical air holed PCF over wide wavelength range has been investigated. Also, the applications and the propagation characteristics of the proposed PCF structure which occurs with the interaction of the fundamental mode and the liquid filled holes have been discussed. © 2014 IEEE.
