“…In recent years, many intriguing phenomena have emerged, for instance, optical coherence lattices, [5] coherent vortex, [6] partially coherent Airy beam (PCAiB), [7] Cosine-Gaussian correlated Schell-model pulsed beams, [8] and so on. As accelerating diffraction-free Airy beams were first observed in 2007, [9,10] the investigations on particular Airy beams, such as their acceleration properties, [11,12] their optical manipulation, [13][14][15][16] and their propagation in different medium, [17] and so on, have become a research hotspot. Recently, partially coherent single Airy [18] and multi-Airy [19] beams which maintain the acceleration properties (rate and range) of coherent counterparts are introduced by Gaussian Schell-model (GSM) beams [20][21][22] as light sources.…”

“…On one hand, the superposition of multi‐Airy beams provides one way to symmetrize the intensity patterns of Airy beams. Thus, many intriguing phenomena, for instance, about such dual Airy beam, [ 24 ] accelerating quad Airy beams, [ 11 ] and Airy vortex beam arrays [ 25 ] have been investigated. Meanwhile, auto‐focusing Airy beams have also been important topics in optical micromanipulation.…”

By applying quadratic and linear phase modulations (QPM and LPM), the propagation properties of the partially coherent dual and quad Airy beams which maintain acceleration in free space are studied. They are generated by superimposing two and four partially coherent Airy beams whose phase is modulated in the source field. It is demonstrated that the trajectories of the partially coherent light beams and the location and number of focal points, along with maximum altitude and range of the trajectories can be easily dominated by adjusting the appropriate values of QPM p and LPM l. Furthermore, for the quad case, the transverse spectral density distribution of lacking side lobes exhibits the structure of the optical frame which may be flipped under certain conditions. Both the peak intensity of the beams and the divergence speed of the optical frame can be managed by choosing the different characteristic transverse width of the beams. These results show an energizing new idea in the manipulation of partially coherent multiple fields of accelerating beams.

“…In general, the spatial distribution of all the slits is designed to create a specific SPP wavefront and subsequently the desired focal field. For example, an Airy phase modulation along the lateral dimension of the beam 19,20 generates a spatially curved SPP-Airy beam near the focus. Although such displacements of the nano-slits generate various structured focal fields, these fields are nonetheless constant and not dynamically controlled.…”

On-chip manipulation of the spatiotemporal characteristics of optical signals is important in the transmission and processing of information. However, the simultaneous modulation of on-chip optical pulses, both spatially at the nano-scale and temporally over ultra-fast intervals, is challenging. Here, we propose a two-dimensional spatiotemporal Fourier transform (FT) method for on-chip control of the propagation of femtosecond optical pulses and verify this method employing surface plasmon polariton (SPP) pulses on metal surface. By varying space- and frequency-dependent parameters, we demonstrate that the traditional SPP focal spot may be bent into a ring shape, and that the direction of propagation of a curved SPP-Airy beam may be reversed at certain moments to create an S-shaped path. Compared with conventional spatial modulation of SPPs, this method offers potentially a variety of extraordinary effects in SPP modulation especially associated with the temporal domain, thereby providing a new platform for on-chip spatiotemporal manipulation of optical pulses with applications including ultrafast on-chip photonic information processing, ultrafast pulse/beam shaping, and optical computing.

“…[ 10,11 ] For generating Airy optical beams, it is highly desirable to precisely control light waves to satisfy the amplitude and phase distributions described by Airy function. Conventional protocols for generating Airy beams rely on the utilization of bulky optical elements, such as spatial light modulators (SLMs), [ 5,9,12,13 ] liquid crystals (LCs), [ 14–16 ] lens, [ 17 ] and phase plate. [ 18,19 ] These schemes suffer from low transmission efficiencies with SLMs or LCs (typically less than 40%), and long device lengths with lens and phase plates.…”

a wide range of applications including optical micromanipulation, [1,2] chip-scaled signal processing, [3,4] microscopy, [5,6] generation of curved plasma channels, [7] light bullet, [8,9] and vacuum electron acceleration. [10,11] For generating Airy optical beams, it is highly desirable to precisely control light waves to satisfy the amplitude and phase distributions described by Airy function. Conventional protocols for generating Airy beams rely on the utilization of bulky optical elements, such as spatial light modulators (SLMs), [5,9,12,13] liquid crystals (LCs), [14-16] lens, [17] and phase plate. [18,19] These schemes suffer from low transmission efficiencies with SLMs or LCs (typically less than 40%), and long device lengths with lens and phase plates. [16-20] Metasurfaces provide an unprecedented approach to control light waves in terms of amplitude, phase, polarization, and so on. The past few years have witnessed the rapid development of optical functional devices and applications with metasurfaces, including polarization control, [21-24] flat lens, [25-30] holographic imaging, [31-33] invisibility cloaks, [34,35] and orbital angular momentum. [36-39] Different from phase-only modulation optical elements and applications, such as lens or holograms, the implementation of Airy beams requires simultaneous amplitude and phase modulation. Recently, metasurfaces offered a compact method to build Airy beam generators due to their great capability to manipulate light waves. Many metasurface configurations, including plasmonic metasurfaces, [40-45] dielectric nano-rods, [46-48] and hyperbolic metamaterials [49] have been developed for Airy beam generation in the past few years. However, most of these schemes use some resonant building blocks to modulate light waves across the resonant frequencies; the resultant phase and amplitude profiles no longer abide by the Airy function out of the resonant frequencies. Consequently, the Airy beams can only be realized within a rather narrow bandwidth around the resonant frequencies. Some efforts have been dedicated to broadening the working bandwidth, but the transmission efficiencies are reduced significantly once the working frequencies deviate from the resonant frequencies. [42,45] The recently reported dielectric metasurfaces have provided a robust approach to increase the transmission efficiency, however, these schemes are purposely designed to enable phase modulation, resulting in low quality of the generated beams due to lack of amplitude modulation. [46-48] Broadband high-efficiency Airy beams have been proposed and experimentally demonstrated Conventional approaches for generating Airy beams rely upon bulky and costly systems, which impede the miniaturization of optical systems. Metasurfaces have provided a compact method to generate Airy optical beams, but the current schemes suffer from the issues of narrow bandwidths and/or low transmission efficiencies. Here, a design strategy of constructing broadband and high-efficiency transmissive Airy optical beam genera...
