Optical bottle beams (OBBs) are beams of light where a dark region is completely surrounded by light, but so far, this is not always the case. In modern OBBs, created by Bessel and vortex beams, nodal surfaces are present leading to a three-dimensional lobed structure in coherent beams. But is this always the case? We use a combination of computational modeling with novel phase retrieval techniques and polarization-dependent wavefront shaping to explore the creation of computer-generated holographic bottle beams. We discuss the creation of such beams, and how to maintain a “perfect bottle”.
