Summary: This paper presents a D-shaped photonic crystal fiber (PCF) sensor based on surface plasmon resonance. Graphene, Gold, and Silver are used in different configurations to enhance the sensor's sensitivity. Numerical simulations show that the gold layer sandwiched between two graphene layers exhibits the maximum wavelength sensitivity of 12600 nm RIU-1 when the refractive index of the analyte ranges from 1.36 to 1.40. The proposed sensor is easy to use and can be placed on the D-shaped surface without filling the fiber holes with the analyte. It is suitable for sensing biological variations due to its strong surface plasmon resonances. The effect of fabrication tolerance on the proposed PCF is also studied. The proposed model is expected to be compatible with bioengineering approaches.

Summary: This paper proposes a D-shaped photonic crystal fiber (PCF) surface plasmon resonance (SPR) sensor to measure the refractive index in visible and near-infrared regions. The use of D-shaped PCF can avoid filling materials and coatings in the hole. The plasma material of sensors is silver, and graphene is coated on the surface of the silver film. The influence of structural parameters on the sensor performance is studied by the finite element method (FEM).

Summary: We present an extrinsic surface plasmon-enhanced refractometer based on cladding mode resonance excitation in a photonic crystal fiber (PCF) with a straight fiber Bragg grating (FBG). By selecting suitable PCF parameters, high sensitivity to changes in refractive index close to that of water can be achieved. The sensor fabrication does not require post-processing and multi-target detection is possible using cascaded wavelength-multiplexed gratings.

Summary: This research article presents a photonic crystal fiber (PCF) based on a surface plasmon resonance (SPR) sensor for detecting refractive index (RI) of unknown analytes. The PCF is modified by placing a plasmonic material layer (gold) outside the PCF, creating a D-shaped PCF-SPR sensor. Numerical investigation using finite element method (FEM) shows that the proposed PCF-SPR sensor exhibits high sensitivity with maximum wavelength sensitivity of 9000 nm/RIU, amplitude sensitivity of 3746 RIU-1, and a sensor resolution of 1 x 10(-5) RIU. The miniaturized structure and high sensitivity make it a promising candidate for detecting RI of analytes ranging from 1.28 to 1.42.

Summary: This paper proposes a surface-plasmon-resonance-based sensor that allows for tuning of the spectral response by adjusting the volume fraction of silver. The sensitivity and resolution of the sensor can be greatly altered by changing the amounts of constituents in the metamaterial. Additionally, the sensor can be used to label the average volume fraction of silver in the metamaterial layer and estimate its effective constitutive parameters.
