“…It is possible to achieve polarizers with high extinction ratio with help of the polarization‐selective property of SPPs and anisotropic scatterers. Polarization‐sensitive plasmonic devices, which show large controllability with high contrast, are successfully demonstrated, directional launching and switching of SPPs, multiplexed plasmonic lenses, polarization‐controlled resonators, SPP beam steering, and caustic beam generation, for instances. Other reports of polarization generators and converters, optical routers, and multiplexed holography show strong potential for wide variety of applications.…”

Polarization is one of the fundamental properties of light, which is inherited from the vectorial nature of electromagnetic waves. Measuring states of polarizations (SOPs) is widely used for remote sensing applications. A number of ultracompact polarimeters that analyze SOPs at a single detection without splitting of incident beams have been demonstrated recently. However, the development of a broadband polarimeter remains challenging due to the resonant feature of their building blocks. Here, an ultracompact polarimeter that retrieves the SOP of incident light with broad operation bandwidth at near-infrared wavelengths is proposed. Surface plasmon polaritons (SPPs) excited by X-shaped aperture arrays are utilized as intensity probes. Full-Stokes parameters are retrieved by detecting the SPP intensities. The proposed polarimeter is demonstrated experimentally and can measure SOPs at wavelengths from 750 nm to 1050 nm. This work can help to develop more compact polarization-sensitive optical systems, such as polarimetry, ellipsometry, and optical routers.

“…When a spiral slit of a certain geometrical order is used, a dynamic phase of azimuthally linear variation caused by the additional optical path is added to the SPP field, which allows the TC of the generated OAM to be flexibly controlled . In recent few years, geometrically rotated nanoslits have been adopted and the introduced geometrical phase provides a new dimension to generate arbitrary OAM states . However, compared with the many studies on the generation of plasmonic OAM states, few studies have been conducted on the superposition states of plasmonic OAMs.…”

states can generate structured spatial light fields via the comprehensive manipulations of the helical phase, polarization, and propagation of the light. Intuitively, the equal-weighted superposition of OAM states with TCs of opposite signs may generate spatial modes of petal-like intensity with nonzero or zero global OAMs, and superpositions of higher-order OAMs may produce wheel-like modes with azimuthal variations of intensity in high dimensions. A variety of methods or devices have been developed to enable the superposition of OAMs. These include liquid crystal q-plates, [1][2][3] spatial light modulators, [4,5] crystal prism pairs, [6] microscopic ring resonators, [7,8] and other optical elements. [9][10][11] Moreover, the progress in OAM superposition has brought about many important applications in classical physics and quantum sciences. Classical applications include particle trapping, [12] optical communications, [13,14] and relativistic laser-matter interactions. [15,16] In the quantum field, important advancements have been made in quantum communications, [17][18][19] quantum information processing, [20,21] and quantum calculations. [22,23] The potential to miniaturize superposed spatial modes of OAM to nanoscale is promising for the implementation of integrated on-chip devices. Metasurfaces consisting of monolayers of subwavelength metallic/dielectric structures have become an efficient way to manipulate light at the subwavelength scale. In recent several years, the study of metasurfaces has attracted great interest in areas as phase-controlled, [24] broadband vectorial holograms, [25] broadband achromatic metalenses, [26] and the coherent control of plasmonic spin-Hall effects. [27] The development of metasurfaces for the manipulation of OAM states has also been studied extensively. [28][29][30][31][32][33][34][35] In the past year, significant progress has been made in achieving arbitrarily controlled OAM superposition states via metasurface engineering. Devlin et al. have proposed the metasurface J-plate to realize the superposition of independent OAM states and to convert SAMs into total angular momentum states. [36] Using a reflective plasmonic metasurface, Yue et al. demonstrated various OAM superpositions in multiple channels by changing the polarization of the illumination. [37,38] By designing a nonlinear plasmonic metasurface for the simultaneous control of the OAM and SAM, Li et al. achieved the OAM superposition of the modes of the second Superposition of orbital angular momentum (OAM) states and the structured intensity are providing new approaches for manipulating optical information and light-matter interactions. While superposition of OAMs in free space has been well studied, further extensions to surface plasmon polariton (SPP) confined in near-field would be crucial for miniaturing and integrating platforms. Here, the plasmonic metasurfaces consisting of rotated nanoslits arranged in a segmented spiral are proposed to realize the superposition of two SPP OAM states. The nanoslit rota...

“…Particularly, for circularly polarized light, the SPPs generated by subwavelength slits are imprinted with a spin-dependent Pancharatnam-Berry (PB) phase which can be tuned by changing the orientation angle of the slits [46,47]. Polarization-controlled dynamical SPP excitation [48][49][50][51][52][53][54][55][56], SPP focusing [46,[57][58][59][60][61][62][63][64][65][66], SPP vortex [21,44,[67][68][69][70][71][72][73], SPP nondiffracting beams [74][75][76], and SPP holography [77,78] have been 2 of 17 realized. Besides, the other degrees of freedom of light-including the wavelength, topological charge, and the spatial frequency-can be taken advantage of to actively control the SPP field [79][80][81][82][83][84][85][86] as well.…”

As the fundamental and promising branch of nanophotonics, surface plasmon polaritons (SPP) with the ability of manipulating the electromagnetic field on the subwavelength scale are of interest to a wide spectrum of scientists. Composed of metallic or dielectric structures whose shape and position are carefully engineered on the metal surface, traditional SPP devices are generally static and lack tunability. Dynamical manipulation of SPP is meaningful in both fundamental research and practical applications. In this article, the achievements in dynamical SPP excitation, SPP focusing, SPP vortex, and SPP nondiffracting beams are presented. The mechanisms of dynamical SPP devices are revealed and compared, and future perspectives are discussed.
