A photonic-crystal fiber (PCF) based on the surface plasmon resonance (SPR) effect with low confinement loss and high sensitivity response is designed and its optical properties analyzed when varying different parameters. The SPR-based PCF design is analyzed to enable control over its light propagation and evanescent properties. In this investigation, gold (Au) is used as a plasmonic material to generate the SPR effect at the interface. The simulation results reveal a maximum sensitivity response of 45,303 nm/RIU with resolution of 7.0634 × 10–6 and low confinement loss of 0.575 dB/cm in the wavelength range from 1.2 to 2 µm. A high figure of merit of 378 with low full-width at half-maxima is also obtained. The proposed structure thus offers ultralow confinement loss and high sensitivity.

探索基于裸芯的光子晶体光纤的光学特性

设计了一种基于表面等离子体激元共振(SPR)效应,具有低限制损耗和高灵敏度响应的光子晶体光纤(PCF),并在改变不同参数时对其光学特性进行了分析。对基于SPR的PCF设计进行了分析,以控制其光传播和e逝特性。在这项研究中,金(Au)被用作等离子体材料,以在界面处产生SPR效应。仿真结果表明,在1.2至2 µm的波长范围内,最大灵敏度响应为45,303 nm / RIU,分辨率为7.0634×10 –6,限制损耗为0.575 dB / cm,低。还获得了378的高品质因数,在半最大值时具有较低的全宽。因此,所提出的结构提供了超低的限制损耗和高灵敏度。
