Optical wavefront shaping -where multiple waves with adjustable phases and amplitudes are sent onto complex media -has revolutionized the study of light in Nanophotonics. Recently, a new type of wavefront shaping was introduced where the extinction rather than the scattered intensity is manipulated. The underlying idea is that upon changing either the phases or the amplitudes of incident beams, the total extinction will change due to interference described by the cross terms between the incident beams. Here, we present the first experimental study of the mutual extinction effect in complex media, in particular, a human hair and a silicon bar. The mutual extinction is readily observed with two incident waves at small angles, depending on the relative phase of the incident beams we observe either nearly zero extinction (mutual transparency) or almost twice the single-beam extinction (mutual extinction) in agreement with theory. We use an analytical approximation for the scattering amplitude starting from a completely opaque object and discuss the limitations of our approximation. We discuss novel applications of the mutual extinction and transparency effects in various fields such as non-line-of-sight communications, microscopy, and biomedical imaging.

“…In these inhomogeneous materials, multiple scattering and interference distort the incident wavefront so strongly that the spatial coherence is immensely reduced [97]. The invention of optical wavefront shaping (WFS) [43], where N multiple waves are incident on a complex sample with adjustable phases and amplitudes, has revolutionized the study of scattering of light in nanophotonics and led to exciting applications, such as transmission optimization [44,67,[98][99][100], light focusing [63,64,93,[101][102][103][104], light absorption and energy density control [72,[105][106][107], and new biomedical imaging techniques [64,[108][109][110].…”

DISSERTATIONto obtain the degree of doctor at the University of Twente, on the authority of the rector magnificus, prof.dr.ir. A. Veldkamp, on account of the decision of the Doctorate Board, to be publicly defended on Tuesday the 10 th of October 2023 at 14.45 by Alfredo Rates Soriano born on the 2 nd of February 1995 in Santiago, Chile. This dissertation has been approved by: Promotors: prof.dr. W.L. Vos prof.dr. A. Lagendijk Cover: Cover inspired by classic book covers. The symbols at the corners represent the random walk made by light in a scattering medium, while the square grids on the sides represent the segments of light modulation. On the back, three symbols appear representing the three projects of the thesis: mutual scattering to control transparency (top), physical unclonable functions (bottom left), and wavefront modulation to characterize objects (bottom right). Concept by Alfredo Rates and design by Paula García Miranda
