Abstract:
Light transport in a highly multimode fiber exhibits complex behavior
in space, time, frequency, and polarization, especially in the presence of mode coupling. The newly developed techniques of spatial
wavefront shaping turn out to be highly suitable to harness such enormous complexity: a spatial light modulator enables precise
characterization of field propagation through a multimode fiber, and by adjusting the incident wavefront it can accurately tailor the
transmitted spatial pattern, temporal profile, and polarization state. This unprecedented control leads to multimode fiber applications in
imaging, endoscopy, optical trapping, and microfabrication. Furthermore, the output speckle pattern from a multimode fiber encodes
spatial, temporal, spectral, and polarization properties of the input light, allowing such information to be retrieved from spatial
measurements only. This article provides an overview of recent advances and breakthroughs in controlling light propagation in
multimode fibers, and discusses newly emerging applications.
