We propose a framework for designing coherent optical environments that enable versatile and dynamic optical manipulation.In contrast to conventional material-based near-field platforms,our approach employs a structured coherent light field,optimized via a backpropagation-based inverse design algorithm,as the manipulation environment.This light-based platform allows a simple control beam,such as a single plane wave or a low-numericalaperture Gaussian beam,to steer micro-objects effectively.By establishing a one-to-one correspondence between control beam parameters(e.g.,phase/polarization of a plane wave)and particle trapping positions,our method enables real-time and versatile control of particles.A wide range of two-and three-dimensional trajectories,including circles,squares,tree-like paths,and epicycle-deferent curves,can be achieved solely by modulating the phase of the control beam.This design strategy for the structured-light environments offers a dynamically reconfigurable,all-optical,and contact-free platform for advanced optical manipulation in free space,with promising applications in nanorobotics,biological probing,and beyond. 展开更多
