Dielectric-loaded surface plasmon polariton waveguides (DLSPPWs) are typically made using nanolithography fabrication methods. In this paper we demonstrate that near-field electrospinning of polymer nanofibers directly onto a gold coated substrate can be used as an alternative method for rapid prototype fabrication of DLSPPWs. Surface plasmon polaritons (SPPs) have been excited directly inside the electrospun fibers using a prism in the Kretschmann-Raether configuration. A scanning near-field optical microscope (SNOM) was used to characterize the propagation of the excited SPP inside the polymer fiber demonstrating the potential for using electrospun polymer fibers as SPP waveguides.
介质加载表面等离子体激元波导（DLSPPWs）通常采用纳米光刻制造方法制备。在本文中，我们证明了将聚合物纳米纤维直接近场静电纺丝到涂金衬底上可作为快速原型制造DLSPPWs的替代方法。使用Kretschmann-Raether配置的棱镜在静电纺丝纤维内部直接激发了表面等离子体激元（SPPs）。使用扫描近场光学显微镜（SNOM）对聚合物纤维内部受激SPP的传播进行了表征，证明了使用静电纺丝聚合物纤维作为SPP波导的潜力。
