摘要

A tunable surface plasmon resonance based on polarization beam splitter (PBS) is proposed by using a dual-core photonic crystal fiber with magnetic fluid. Propagation characteristics of the PBS are analyzed by finite element method. The resonance wavelength which satisfied the phase matching condition shifts when change external magnetic field. Simulation results show that incident light wavelengths with a wide range of 1.45-1.55 μm can be split, the minimum bandwidth of 168 nm and the extinction ratio can reach to — 128 dB when external magnetic field range 400-760 Oe at the same structure.These properties make the splitter we proposed a competitive candidate for fiber beam splitter.
