Dynamically tunable optical lattices based on interference of two linearly chirped elliptical Airyprime vortex beams

Whether an optical lattice featuring enhanced focusing capability, multiple adjustable peak intensity profiles, and the propensity to recover after traversing an obstacle exists is herein addressed. A systematic elucidation is provided regarding the characteristics of a controllable optical lattice generated via the interference of two linearly chirped elliptical Airyprime vortex beams. Initially, the modulation of the initial planar light intensity distribution, the position and pattern of the focal-peak plane, and the cross configuration inherent in the intensity pattern is achieved by varying the primary ring radius and the elliptical factor. The introduction of the topological charges and the linearly chirped factors is demonstrated to impart a variety of morphological transformations to the optical lattices. This permits a more refined adjustment of the beams profiles at the focal-peak planar position, such that the lattices morphology becomes tunable on both macroscopic and microscopic scales. Moreover, the auto-healing property of the optical lattices, which is inherited from Airyprime beams, is experimentally verified. It is shown that, following the disruption of its local structure by external perturbations, the originally expected intensity distribution reemerges over a relatively short propagation distance. Additionally, a novel interference modality is employed to enhance the focal-peak intensity of the optical lattice. The balance between improvement in focusing capability and a more dispersed intensity distribution during propagation achieves diversified application requirements. The aforementioned capabilities for parameter modulation together with the auto-healing characteristics confer upon the controllable optical lattice considerable potential for applications in frontier fields such as quantum gas microscopy, the manipulation of microscale and nanoscale particles, and high density quantum simulation.
