A single-stage reconfigurable 2-D optical perfect-shuffle network system using multiplexed phase holograms

Author(s): Kyongsik Choi Byoungho Lee

Abstract:

“We propose a single-stage reconfigurable two-dimensional (2-D) optical perfect-shuffle network system (PSNS) using multiplexed phase holograms on one phase-type spatial light modulator (SLM). Phase holograms are used that adopt dynamically combined and multiplexed holograms to implement 2-D perfect shuffling of optical images. Experimentally, we demonstrate the proof-of-principle of the proposed single-stage reconfigurable 2-D optical PSNS using a collimated light source, the multiplexed phase holograms on a phase-type SLM, and a Fourier transform lens.”

Structure and scaling of helical modes of light

Author(s): Steven Sundbeck, Ilya Gruzberg, and David G. Grier

Abstract:

“Modes of light that contain topological defects such as screw dislocations can be focused into optical traps with interesting and useful properties. The way in which the intensity distribution within helical modes of light varies with topological charge is discussed, and new scaling predictions for their radial profiles that are consistent with experimental observations are introduced.”
