“…The lateral shape of the high-order Bessel beam is controlled by order of the spiral phase mask (Figure 7E) [82]. Adjustable Airy trajectories in the 3D space are achieved by rotation of the cubic phase mask (CPM) on the SLM screen in tomographic microscopy (Figure 7F) [83]. In contrast to the mechanical rotation of the phase elements, directly rotating the phase pattern on the SLM screen avoids introducing optical misalignment, especially for microscopies.…”

The light propagation in the medium normally experiences diffraction, dispersion, and scattering. Studying the light propagation is a century-old problem as the photons may attenuate and wander. We start from the fundamental concepts of the non-diffracting beams, and examples of the non-diffracting beams include but are not limited to the Bessel beam, Airy beam, and Mathieu beam. Then, we discuss the biomedical applications of the non-diffracting beams, focusing on linear and nonlinear imaging, e.g., light-sheet fluorescence microscopy and two-photon fluorescence microscopy. The non-diffracting photons may provide scattering resilient imaging and fast speed in the volumetric two-photon fluorescence microscopy. The non-diffracting Bessel beam and the Airy beam have been successfully used in volumetric imaging applications with faster speed since a single 2D scan provides information in the whole volume that adopted 3D scan in traditional scanning microscopy. This is a significant advancement in imaging applications with sparse sample structures, especially in neuron imaging. Moreover, the fine axial resolution is enabled by the self-accelerating Airy beams combined with deep learning algorithms. These additional features to the existing microscopy directly realize a great advantage over the field, especially for recording the ultrafast neuronal activities, including the calcium voltage signal recording. Nonetheless, with the illumination of dual Bessel beams at non-identical orders, the transverse resolution can also be improved by the concept of image subtraction, which would provide clearer images in neuronal imaging.

“…[ 3–5 ] Since Airy beam was firstly demonstrated in experiment, [ 3 ] these unique properties facilitate its applications in particle manipulation, [ 6 ] light bullets, [ 7 ] and high‐resolution microscopy. [ 8,9 ] Furthermore, Airy beam plays a critical role in combination with other structured light. In particular, Airy beam can be embedded with a helical phase‐front, contributing to the so‐called Airy vortex beam (AVB).…”

Airy beam and Airy vortex beam with intriguing characteristics have been extensively studied in linear optics, while their dynamic nonlinear conversion has rarely been explored and remains challenging. Here, through the collaboration of binary mask engineered nonlinear photonic crystal and space‐variant liquid‐crystal geometric phase element, second‐harmonic Airy beam and Airy vortex beam can be generated in a switchable manner. Electrical‐controlled loading of orbital angular momentum (OAM) into fundamental wave unlocks the flexibility of nonlinear process, which is well investigated in theory and further verified by experiment. Wavelength transformation, OAM conversion, and propagation trajectory inflection are realized simultaneously. This offers a convenient and universal strategy for dynamic nonlinear generation and shows great potentials in optical manipulation and information processing.

“…Compared with Gaussian beams, non-diffraction and self-healing beams, such as the Bessel beam, Airy beam, and abrupt autofocusing beam, are able to maintain propagation properties up to long propagation distances [24]. The Airy beam has spatially asymmetric intensity distribution, parabolic propagation trajectory, and self-acceleration behavior, which was theoretically found [25] by Berry and Balazs in 1979 and experimentally observed [26] by Siviloglou et al in 2007. In recent years, Airy beams have attracted large interest in various applications, including the generation of curved plasmonic channels [27], micromachining of curved profiles [28], and 3D super-resolution imaging [29,30]. In optical manipulation techniques, particularly, Airy beams exhibit unique optical properties and have been employed for optical snow blowers [14] and optical conveyors [17,31], including guiding, pushing, and trapping.…”

Cubic-Phase Metasurface for Three-Dimensional Optical Manipulation

et al. 2021

View full text Add to dashboard Cite

The optical tweezer is one of the important techniques for contactless manipulation in biological research to control the motion of tiny objects. For three-dimensional (3D) optical manipulation, shaped light beams have been widely used. Typically, spatial light modulators are used for shaping light fields. However, they suffer from bulky size, narrow operational bandwidth, and limitations of incident polarization states. Here, a cubic-phase dielectric metasurface, composed of GaN circular nanopillars, is designed and fabricated to generate a polarization-independent vertically accelerated two-dimensional (2D) Airy beam in the visible region. The distinctive propagation characteristics of a vertically accelerated 2D Airy beam, including non-diffraction, self-acceleration, and self-healing, are experimentally demonstrated. An optical manipulation system equipped with a cubic-phase metasurface is designed to perform 3D manipulation of microscale particles. Due to the high-intensity gradients and the reciprocal propagation trajectory of Airy beams, particles can be laterally shifted and guided along the axial direction. In addition, the performance of optical trapping is quantitatively evaluated by experimentally measured trapping stiffness. Our metasurface has great potential to shape light for compact systems in the field of physics and biological applications.
