“…Besides, the superposition of vortex beams plays an important role in many cutting-edge optical applications due to the rich polarization properties. [31][32][33][34][35] Benefiting from the rich polarization information generated by the coherent superposition of vortex beams which carry OAM, the designed reflective metasurface polarimeter was evaluated at an operating wavelength of 650 nm by Ma et al, 36 but the behavior of utilizing the superposition of different topological charges to determine the handedness of the incident light weakens its value in practical applications. Jiang et al 37 produced a superimposed Bessel vortex beam at 0.14 THz using a metasurface-like array of metallic waveguides, while the obtained high quality beams carrying OAM are merely detectable for linear polarization states.…”

“…With extensive application potential in various fields including microfabrication, optical tweezers, light bullets, and medical imaging, etc., research on accelerating optical trajectories has attracted considerable interest. − Bessel-like beams, as a novel class of accelerating optical beams, propagate along predefined arbitrary trajectories and possess three fascinating properties, namely, self-acceleration, diffraction-free propagation, and self-healing, revealing an emerging research direction. , Typically, conventional optical setups, for example, the spatial light modulators for generating Bessel-like beams, − are bulky and low diffraction efficiency, and lack flexible trajectory control capabilities, which makes it challenging for the miniature chip integration and hinders their further applications. The emergence of metasurfaces with ultrathin flat structures alleviates this issue, − and provides a convenient way to generate accelerating beams by modulating free-space light. − …”

On-chip integrated meta-optics promise to achieve high-performance and compact integrated photonic devices. To arbitrarily engineer the optical trajectory along the propagation path in an on-chip integrated scheme is of significance in fundamental physics and various emerging applications. Here, we experimentally demonstrate an on-chip metasurface integrated on a waveguide to enable predefined arbitrary optical trajectories in the visible regime. By transformation of the transverse phase to generate longitudinal mapping, the guided waves are extracted and molded into any different optical trajectories (parabola, hyperbola, and cosine). More intriguingly, predefined polarization states with longitudinal variation are also successfully imparted along the trajectory. Owing to the on-chip propagation scheme, the trajectories are uniquely free from zero-order diffraction interference, naturally having a higher signal-to-noise ratio beyond conventional free-space forms. Overall, such on-chip optical trajectory engineering allows for miniaturized integration and can find paths in potential applications of complex optical manipulation, advanced laser fabrication, and microscopic imaging.

Exploring and taming the diffraction phenomena and divergence of light are foundational to enhancing comprehension of nature and developing photonic technologies. Despite the numerous types of nondiffraction beam generation technologies, the 3D deformation and intricate wavefront shaping of structures during propagation have yet to be studied through the lens of nanophotonic devices. Herein, the dynamic conversion of a circular Airy beam (CAB) to a Bessel beam with a single‐layer spin‐selective metasurface is demonstrated. This spatial transformation arises from the interplay of 1D local and 2D global phases, facilitating the 3D control of non‐diffractive light fields. An additional overall phase gradient and orbital angular momentum are introduced, which effectively altering the propagation direction and transverse fields of complex amplitude beams along the optical path. The manifested samples exhibit superior defect resistance, laying a crucial application in micro/nanolithography technologies. This approach expands the in‐plane spin‐selective mechanism and leverages the out‐of‐plane propagation dimension, allowing for integrated high‐resolution imaging, on‐chip optical micromanipulation, and micro/nanofabrication within a versatile nanophotonic platform.
