“…Such finite energy beams will only maintain their shape over a finite propagation distance. Specifically, we realized the well-known "self-accelerating" plasmonic Airy beam, previously proposed [12] and demonstrated in [13][14][15][16], together with CG and local-cosine-Gauss (LCG) plasmonic beams, previously demonstrated in [20]. We note that in some of the cases above, the resulting structure formed by our method could be seen as similar to those used by others; still the approaches that were used are completely different.…”

“…Moreover, SPPs are usually excited by free-space beams, and in this case there is a wave-vector difference between the two beams that needs to be compensated. In the last couple of years, efforts to control the SPP wave properties have been made, and unique plasmon beams, such as "self-accelerating" Airy beams [12][13][14][15][16], plasmon beams accelerating along arbitrary caustic trajectories [17], and shape-preserving ("diffraction-free") Bessel [18,19] and cosine-Gauss (CG) [20] plasmon beams, have been realized. However, the realization of each one of these plasmon beams was based on a different ad hoc method, specifically tailored, and therefore limited only to that specific plasmonic beam.…”

Shaping plasmonic light beams with near-field plasmonic holograms

We introduce a new class of plasmonic holograms for the near field. These holograms provide complete control of the amplitude and phase of surface plasmon polaritons (SPPs), thereby enabling the generation of any desired plasmonic light beam. The scheme is based on a two-dimensional near-field plasmonic hologram, which couples the SPP from free space into the metal-dielectric interface, and also sets the attributes of the plasmonic beam. We demonstrate the concept for a wide variety of plasmonic beams with different qualities-in particular, "self-similar" Hermite-Gauss beams, "nondiffracting" cosine-Gauss beams, and "self-accelerating" Airy beams.

“…It was suggested in 2010 that the unique properties of the Airy beam would also be supported in a two‐dimensional system as a surface wave, e.g. the Airy plasmon . This led to the first generation of a plasmonic Airy beam in 2011 by three different groups, and in three different methods.…”

“…The inplane diffraction method, introduced by Li et al. allows for a greater amount of control on the phase of the generated SPP, the ability to handle a broader spectral SPPs excitation , and is not limited by the above‐mentioned coupling condition. This fact makes it more versatile for a variety of applications.…”

Surface‐plasmon‐polariton waves are two‐dimensional electromagnetic surface waves that propagate at the interface between a metal and a dielectric. These waves exhibit unusual and attractive properties, such as high spatial confinement and enhancement of the optical field, and are widely used in a variety of applications, such as sensing and subwavelength optics. The ability to precisely control the spatial and spectral properties of the surface‐plasmon wave is required in order to support the growing interest in both research and applications of plasmonic waves, and to bring it to the next level. Here, we review the challenges and methods for shaping the wavefront and spectrum of plasmonic waves. In particular, we present the recent advances in plasmonic spatial and spectral shaping, which are based on the realization of plasmonic holograms for the optical nearfield.

“…An interesting property of a plasmonic airy beam is self-healing, namely, the beam recovers its shape after passing through a defect. We refer readers to a latest review paper for more insights on the plasmonic airy beams [90]. A nonperfectly matched Bragg diffraction method was also developed for diffraction-free SPP beams [91].…”

Light manipulation with encoded plasmonic nanostructures

2014

-Plasmonics, which allows for manipulation of light field beyond the fundamental diffraction limit, has recently attracted tremendous research efforts. The propagating surface plasmon polaritons (SPPs) confined on a metal-dielectric interface provide an ideal two-dimensional (2D) platform to develop subwavelength optical circuits for on-chip information processing and communication. The surface plasmon resonance of rationally designed metallic nanostructures, on the other hand, enables pronounced phase and polarization modulation for light beams travelling in three-dimensional (3D) free space. Flexible 2D and free-space propagating light manipulation can be achieved by encoding plasmonic nanostructures on a 2D surface, promising the design, fabrication and integration of the nextgeneration optical architectures with substantially reduced footprint. It is envisioned that the encoded plasmonic nanostructures can significantly expand available toolboxes for novel light manipulation. In this review, we presents the fundamentals, recent developments and future perspectives in this emerging field, aiming to open up new avenues to developing revolutionary photonic devices.
