Abstract :
In this paper, a surface plasmon resonance nanosensor based on photonic crystal fiber is introduced, which is capable of detecting high refractive indices and at the same time has appropriate sensitivity. The proposed structure consists of an air hole ring and a hole ring made of gold and TiN. In order to increase the sensitivity and efficiency of the sensor, two elliptic-shaped grooves are created at the top and bottom of the structure and a thin layer of gold is placed on them. Also, the two sides of the structure are polished and a thin layer of ITO is placed on them. The combination of these materials and the designed geometry has caused the phase matching conditions to be established properly and to detect the desired refractive indices of the analyte. The finite element method has been used for numerical simulation, mode analysis, and investigation of the surface plasmon resonance characteristics of the photonic crystal fiber sensor. Numerical results show that the sensor has a very good wavelength sensitivity of 6000 nm⁄RIU, a resolution of , and a range sensitivity of 572 . The detectable refractive index range of the sensor is between 1.4 to 1.6, which is a high value. Based on the results obtained, the proposed sensor is an excellent option for medical and chemical diagnostic applications.
