Abstract

We present a theoretical method, together with its experimental confirmation, to obtain structures of light by connecting diffraction-resistant cylindrical beams of finite lengths and different radii. The resulting ``LEGO-like beams{''} can assume, on demand, various unprecedent spatial configurations. We also experimentally generate some of them using a computational holographic technique and a spatial light modulator. Our method of linking together various pieces of light can find applications in all fields where structured light beams are needed, in particular, optical tweezers (e.g., for biological manipulations), optical guiding of atoms, control of orbital angular momentum of light, holography, lithography, nonlinear optics, and interaction of electromagnetic radiation with Bose-Einstein condensates, besides, in general, the field of localized waves (nondiffracting beams and pulses).
