15 November 2018Enhancement of plasma resonance in a Hi-Bi D-shaped photonic crystal fiber SPR sensor
A D-shaped fiber surface plasmon resonance (SPR) sensor based on a Hi-Bi photonic crystal fiber (PCF) is investigated with finite element method. Through changing the size of the air holes beside the fiber core, it is found that the Hi-Bi structure can enhance the plasmon resonance at mid-infrared wavelength. The effect of the two fiber core side holes as well as the different gold film thickness on plasmon resonance is numerically investigated. A high and sharp loss peak is achieved, which indicates that the sensor should have high accuracy. The sensitivity of this D-shaped PCF sensor is obtained to be 8920nm/RIU in the range of 1.37 to 1.39 and the power sensitivity is 154 dB/(cm·RIU) in the range of 1.33 to 1.36. Particularly, near 1.36, with the detection limit of 0.1 nm the resolving power of the sensor is lower than 10-4 RIU with a figure of merit of 28.6.
