Paper Abstract

Holographic control of randomized light opens up new ways for imaging and manipulation. We present a powerful approach towards understanding of light propagation through multimode optical fibres and control of the signal at the fibre output. We introduce an experimental geometry allowing analysis of the light transmission through the multimode fibre and subsequent beam-shaping. We show how to generate arbitrary output optical fields within the accessible field of view and range of spatial frequencies. We also show that this technology has applications in biophotonics. As an example, we demonstrate the manipulation of colloidal microparticles.
