“…In the last several decades, many experiments and simulations have been carried out to concern the self-healing properties of the non-diffracting beam. Beyond the classical Bessel beam, the self-healing of Airy and its family beams has also been studied [10][11][12][13][14][15][16][17]. Furthermore, the other ingeniously designed structured beams based on fundamental non-diffracting beams [18], such as caustic beam [19], Mathieu beam [20], Weber beam [21], Pearcey beams [22], pillar beam [23], optical ring lattice [24], helico-conical beams [25], can recover the intensity profile of the optical field.…”

Optical self-healing is a repairing phenomenon of a beam in the propagation, as it is perturbed by an opaque object. In this work, we demonstrate experimentally and theoretically that the moiré distributed dual-microlens array enables to generate optical fields with better healing ability to withstand defects than their counterparts of a single microlens array. By utilizing the double parameter scanning method, the self-healing degree of the optical field is significantly affected by both the interval distance and the relative angle of the dual-microlens arrays. The self-healing level is decreased significantly by lengthening the interval between the two microlens array with a small twist angle, while increasing the angle enhances the self-healing degree. Further study manifests the self-healing process with respect to the size and central location of the obstacle. The research results provide a simple and effective method to generate self-healing optical wave fields, which have potential applications including optical communication, assisted imaging technology, and even intense laser physics.

“…Derived from Helmholtz wave equation, Airy beam is one of its nondispersive solutions which is blessed with exotic characteristics such as nondiffracting, self-bending transmission, [1] self-acceleration, [2,3] and self-healing. [4,5] Airy light with finite energy was first realized by the truncation of ideal Airy beam by Siviloglou through an exponential aperture. [6] After that, truncated Airy beams are able to be applied in a variety of optical fields, such as imaging, [7,8] optical micromanipulation, [9] oscillator, [10] production of curved plasma, [11] self-focusing beams, [12,13] and optical bullets.…”

Introducing vortices into an Airy beam by the interference between the lobes of the Airy beam for the first time, the modulation of Airy vortices is experimentally and theoretically investigated by electromagnetically induced transparency (EIT) effect and changing the number of side lobes of the Airy beam. The formation and disappearance of vortices in Airy beams can be caused by changing the number of side lobes. The EIT effect can induce the movement of vortex phase singularity by regulating the intensities of lobes in Airy beams. However, changing the number of side lobes can change the energy distribution of the lobes through the energy flow due to the self-healing of Airy beams, thus causing the displacement of vortex phase singularity. In addition, the simulation of the Poynting vector shows that the less the side lobes are blocked, the more energy can be retained in the main lobe and the unblocked side lobes, so that the overall shape of the Airy beam can be better maintained. Such studies provide a new method to acquire and adjust Airy vortex beams and can be applied in the realm of optical micromanipulation.

“…In addition, paraxial accelerating or partial Airy ring cutting within an aperture can further enhance the intensity contrast or focal depth through the self‐healing of the AAF beam. [ 51–55 ] Meanwhile, the robustness of AAF properties was revealed for complicated beams, e.g., superimposed multiple beams, showing the effect of beam number on the enhancement of autofocusing peak intensity and superior stability performance. [ 56–60 ]…”

Optical lattices have been widely used from classical to quantum physics. The tunable and scalable fabrication of lattices would be of great significance in lattice‐based multipartite applications. This work demonstrates first that a circular Airy beam (CAB), which has the peculiar properties of self‐healing and abrupt autofocusing, can be used to generate two‐dimensional (2D) optical lattices in propagation when encoded by a programmable spatial mask, resulting in the formation of large‐scale and tunable optical lattices with both axis and axial symmetry, and even high‐orbital kaleidoscope shapes. The efficient diffraction of CAB during the spatial crosstalk with the mask enables the realization of tunable lattices with rich periodicity and complexity. The study shows a flexible method to manipulate lattices with large‐scale and versatile structures for potential applications in integrated and scalable optical and photonic devices.
