Imaging properties of Fresnel zone plate-like surface plasmon polariton launching lenses.
A general design method of Fresnel zone plate-like surface plasmon polariton launching lenses (SPPLLs) with an arbitrary phase correction step is proposed, which can implement imaging between the far-field light and surface plasmon polaritons (SPPs). The imaging properties of half-wave SPPLLs, including the resolution power, object-image relationships, and aberrations, are investigated by using a simulation method based on Huygens-Fresnel principle with SPP point source model. The results show that SPPLLs are suitable for the connection between plasmonic and conventional diffraction-limited photonic devices.
