“…Moreover, there have been very few attempts to investigate a systematic design method for multi-focal MFZPs even though such a method could have a huge impact on improvements in laser micro-machining, optical trapping, chemical sensing, biomedical sensing, confocal collimation, achromatic optics, etc. [14][15][16][17][18][19][20][21]. Thus, we think that this field merits additional research.…”

Abstract:We propose a novel design method for multi-focal metallic Fresnel zone plates (MFZPs), which exploits the phase selection rule by putting virtual point sources (VPSs) at the desired focal points distant to the MFZP plane. The phase distribution at the MFZP plane reciprocally formed by the VPSs was quantized in a binary manner based on the phase selection rule, thereby leading to a corresponding on-off amplitude pattern for the targeted MFZP. The resultant phase distribution was dependent on the complex amplitudes of the VPSs, so that they could be determined from the perspective of both multi-focal functionality and fabrication feasibility. As a typical example, we utilized the particle swarm optimization algorithm to determine them. Based on the proposed method, we designed and numerically analyzed two types of novel MFZPs-one for a monochromatic multi-focal application and the other for a multi-chromatic mono-focal application-verifying the effectiveness and validity of the proposed method. We also fabricated them onto Au-deposited glass substrates, using electron beam evaporation and a focused ion beam milling process. We experimentally characterized them and also verified that they successfully demonstrated their feasibilities. The former produced distinct hot spots at three different focal distances of 10, 15, and 20 µm for monochromatic incidence at 650 nm, and the latter produced a single hot spot at a focal distance of 15 µm for multi-chromatic incidence at 660, 532, and 473 nm. The experimental results were also in good agreement with their corresponding numerical results. We expect that both MFZPs will have various applications, such as laser micromachining, optical trapping, biomedical sensing, confocal collimation, achromatic optics, etc.

“…Kano et al reported the first experimental result concerning an efficient excitation of local SPPs, by using the zeroth-order BB [15]. More recently, radially-polarized BBs have been demonstrated to provide the TM polarization required for the effective coupling to the SPPs, which can be used as a virtual probe for the two-photon fluorescence microscopy [16]. We point out that the evanescent BBs can be obtained irrespective of the transverse profile of the radially-polarized impinging beam [17][18][19].…”

Abstract:We report on the existence of nondiffracting Bessel surface plasmon polaritons (SPPs), advancing at either superluminal or subluminal phase velocities. These wave fields feature deep subwavelength FWHM, but are supported by high-order homogeneous SPPs of a metal/dielectric (MD) superlattice. The beam axis can be relocated to any MD interface, by interfering multiple converging SPPs with controlled phase matching. Dissipative effects in metals lead to a diffraction-free regime that is limited by the energy attenuation length. However, the ultra-localization of the diffracted wave field might still be maintained by more than one order of magnitude.

“…Radially polarized light can play a very important role in many research fields, such as Raman spectroscopy [1], optical ray generation [2][3][4], nonlinear microscopy [5], and microfabrication [6], and also for THz applications [7,8]. Surface plasmon polaritons (SPPs) excited on a metallic conical structure can realize adiabatic compression when a radial mode, also known as TM 0 mode, is excited on the cone [9,10].…”

We report on the possibility of realizing a radial mode on a metallic conical structure by means of a linearly polarized incident wave. This result is utilized for observing surface plasmon polaritons adiabatic compression on a tapered conical nanostructure. The ingredients for radial mode generation are described in terms of phase-matching of the components of the electromagnetic field. We conclude by showing the robustness of this approach, explaining the polaritonic behavior as a function of the device geometry.
