This study proposes a photonic crystal fiber made of fused silica glass, with the core infiltrated with chloroform as a new source of supercontinuum (SC) spectrum. We numerically study the guiding properties of the fiber structure in terms of characteristic dispersion and mode area of the fundamental mode. Based on the results, we optimized the structural geometries of the CHCl3-core photonic crystal fiber to support the broadband SC generations. The fiber structure with a lattice constant of 1 μm, a filling factor of 0.8, and the diameter of the first-ring air holes equaling 0.5 μm operates in all-normal dispersion. The SC with a broadened spectral bandwidth of 0.64 to 1.80 μm is formed by using a pump pulse with a wavelength of 850 nm, 120 fs duration, and power of 0.833 kW. That fiber would be a good candidate for all-fiber SC sources as cost-effective alternative to glass core fibers.

Abstract A high sensitivity near-infrared photonic crystal fiber (PCF) refractive index sensor based on surface plasmon resonance (SPR) is proposed in this paper. The sensing performance of the PCF refractive index sensor is calculated and analyzed by using the finite element method (FEM). The coated metal material selects for chemically stable gold, which is used to induce SPR. The resonant coupling will occurs when the phase matching condition is met between the surface plasmon polariton (SPP) mode and the fundamental mode. The influence of the diameter of the central hole and the thickness of the gold film on the resonance wavelength and the confinement loss was studied. Numerical results demonstrate that the average sensitivity of the sensor can reach to 3200nm/RIU, which can be used in the field of refractive index detecting.
