Aberrations of light are commonly known as undesired effects in different applications, including optical trapping. However, here we demonstrate how to take advantage of controlled spherical aberration in order to shape extended optical trapping landscapes, fully-structured in three-dimensional (3D) space and embedding transverse as well as longitudinal electric field contributions. We numerically analyze the light field customization by the simple means of including glass plates in a counter-propagating trapping configuration, presenting sculpted intensity as well as 3D polarization ellipse structures. Experimentally, we prove the realized counter-propagating optical structure by particle velocimetry as well as the analysis of scattered light of optically guided micro-particles. Finally, we demonstrate the potential of our approach by creating extended 3D particle assemblies.

光的像差通常被称为不同应用中的不良影响，包括光阱。然而，在这里我们展示了如何利用受控球差来塑造扩展的光学捕获景观，在三维 (3D) 空间中完全结构化并嵌入横向和纵向电场贡献。我们通过在反向传播捕获配置中包含玻璃板的简单方法对光场定制进行数值分析，呈现雕刻强度以及 3D 偏振椭圆结构。在实验上，我们通过粒子测速法以及光导微粒散射光的分析证明了实现的反向传播光学结构。最后，
