Abstract

In this paper, a novel silicon dual-core photonic crystal fiber (Si-DC-PCF) polarization beam splitter (PBS) based on surface plasmon resonance effect is proposed. The mode coupling characteristics between the X and Y-polarized even and odd modes and surface plasmon polariton mode are analyzed by using the finite element method and coupled-mode theory. The influences of the structure parameters of the Si-DC-PCF on the coupling length and coupling length ratio are investigated. The normalized output power of the X and Y-polarized modes in the cores A and B and the corresponding extinction ratio are also discussed. By optimizing the structure parameters of the Si-DC-PCF, the PBS length of 192 μm and bandwidth of 830 and 730 nm in the cores A and B are achieved. It is believed that the proposed Si-DC-PCF PBS can find important applications in the mid-infrared laser and sensing systems.
