Harnessing coherent-wave control for sensing applications
Pablo Jara, Arthur Goetschy, Hui Cao +1
Imaging techniques such as functional near-infrared spectroscopy (fNIRS) and diffuse optical tomography (DOT) achieve deep, non-invasive sensing in turbid media, but they are const…
Generalized Time-Reversal for Pulse Control in Diffusive Media
Rohin E. McIntosh, Arthur Goetschy, Alexey Yamilov +3
Time-reversal symmetry allows waves to retrace their paths through complex media and refocus at their origin. However, incomplete capture and reversal of scattered waves often limi…
Open transmission channels in multimode fiber cavities with random mode mixing
Guy Pelc, Shay Guterman, Rodrigo Gutiérrez-Cuevas +3
The transport of light in disordered media is governed by open transmission channels, which enable nearly complete transmission of the incident power, despite low average transmiss…
Optimal Targeted Mode Transport in Complex Wave Environments: A Universal Statistical Framework
Cheng-Zhen Wang, John Guillamon, Ulrich Kuhl +4
Recent advances in the field of structured waves have resulted in sophisticated coherent wavefront shaping schemes that provide unprecedented control of waves in various complex se…
Spectral Width of Maximum Deposition Eigenchannels in Diffusive Media
Rohin E. McIntosh, Arthur Goetschy, Nicholas Bender +4
The maximum deposition eigenchannel provides the largest possible power delivery to a target region inside a diffusive medium by optimizing the incident wavefront of a monochromati…
