Abstract In this article, a surface plasmon-based hexagonal photonic crystal fiber sensor is numerically computed and studied. Metallic layer thickness and lattice period are optimized to 30 nm and 1.75 µm respectively to enhance the sensor performance. Sensor sensitivity is obtained by employing the finite element method by enclosing the structure with a perfectly matched layer. This studied sensor uncovers the wavelength sensitivity of 8000nm/RIU, amplitude sensitivity of 3959 /RIU, and minimum detection ability of 1.25x10− 5 RIU for the analyte refractive index range from 1.36 to 1.40. The simulated results’ variations are also analyzed by altering the metallic layer thickness, lattice period, and air hole diameter. The computed PCF sensor might be a promising aspirant in the area of chemical sensing, bio-molecule detection, and biological sample recognition.

Abstract In this paper, a photonic crystal fiber sensor is proposed which have four-opening channels that support surface plasmon resonances. By detecting the optical spectrum of leakage from the fiber core to the four regions created on its periphery, the sensitivity of the sensor can be assessed. Gold is used as the plasmonic material in the infrared wavelength range on the Titanium oxide film which is used as a substrate layer to increase the coupling and adhesion. Influences of structural parameters on the sensor performance are investigated by the Finite Difference Element method. Sensitivities for refractive index of 1.34-1.44 for wavelength ranges (690-1500 nm) with maximum wavelength sensitivity of 25,600 nm / RIU and maximum amplitude sensitivity and 7367 ( RIU-1 ) and figure of merit (FOM) of 547 ( RIU-1 ) have been calculated. In addition to high sensitivity, great FOM value of this sensor is an important feature. This sensor can be used to identify chemicals and biomolecules.
