Controlling spatial coherence with an optical complex medium

Control over optical spatial coherence is a key requirement in diverse applications including imaging, trapping, and communications. Current approaches to controlling are constrained by speed or limited single pair of fields. Here, we propose method achieve single-shot control the between an arbitrary number Our employs multi-port linear device, which realize shaping wavefront input light fields transmitting them through complex medium. To demonstrate capabilities our method, experimentally 3x3-port system use it generate three output beams with desired mutual correlations.
