An ultra-broad band single-polarization single-mode photonic crystal fiberis investigated based on zero order Surface Plasmon Polariton (SPP) mode by using the full vector finite element method. Highly wavelength-dependent transmission is obtained because of the bonding zero-order SPP mode stimulated over the interface of gold/liquid. With a filled refractive index (RI) of 1.52, the polarization extinction is higher than 30dB/cm among a large bandwidth of 360 nm in the second communication window. Meanwhile, the linear relationship between the resonant wavelength of the bonding zero-order SPP mode and the RI value of the filled liquid, make it a good candidate for liquid RI sensor with high linearity and sensitivity.
We proposed a closed-form all-in-fiber SCHF-SPR sensor. Using the dual-core directional microstructure for reference, we add a metal layer in the left core to directly enhance the overlapping area of the core mode and plasmonic mode. A theoretical analysis is carried out to simulate the resonant wavelength shift corresponding to RI. An average sensitivity of 2390.91nm/RIU in the RI range 1.33-1.43, and 9294.55nm/RIU in 1.44-1.54 with high linearity and sensitivity is achieved. This SCHF-SPR sensor has a good sensing performance on RI among the existing RI sensors.
