Paper Abstract

Microscopic structuring and organization of matter utilizing optically induced forces has a high potential to enable novel material properties and photonic features. We briefly review two promising classes of light fields that combine a high degree of order with exciting propagation properties, and demonstrate applications in optical micromanipulation and the creation of refractive index gratings in photorefractive materials. While the class of nondiffracting beams allows for axially extended optical potential landscapes and corresponding structuring of the refractive index, the class of selfsimilar beams offers continuous diffraction during propagation that can be exploited for two- and three-dimensional optical organization. We demonstrate how the transverse organization of the structured light fields can be transferred to corresponding structuring of bulk material and colloidal systems.
