讲座简介：
Structured light fields possess designed spatial textures in amplitude or polarization. The most commonly used structured light field is an optical vortex with an annular spatial intensity form and an orbital angular momentum (OAM). An optical quasiparticle is emerging as a structured light field with topologically protected polarization textures. To date, these structured light fields have been widely investigated in fundamentals and applications in materials science: for instance, optical trapping and manipulation, super-resolution microscopy, and materials fabrication.
In this presentation, we review the state-of-the-art structured light fields, and we also demonstrate a new approach for materials manipulation with structured light fields.
