A fundamental manifestation of wave scattering in a disordered medium is the highly complex intensity pattern the waves acquire due to multi-path interference. Here we show that these intensity variations can be entirely suppressed by adding disorder-specific gain and loss components to the medium. The resulting constant-intensity waves in such non-Hermitian scattering landscapes are free of any backscattering and feature perfect transmission through the disorder. An experimental demonstration… 

2 Constant-Intensity Waves and Modulation Instability in Inhomogeneous Continuous Media

When waves propagate through a non-uniform potential landscape their interference typically gives rise to a complex intensity pattern. In this chapter we review our work on how to entirely suppress

Constant-Intensity Waves in Non-Hermitian Media

When waves propagate through a non-uniform potential landscape their interference typically gives rise to a complex intensity pattern. In this chapter we review our work on how to entirely suppress

Scattering-free pulse propagation through invisible non-Hermitian media

We demonstrate a new design principle for unidirectionally invisible non-Hermitian structures that are not only invisible for one specific wavelength but rather for a broad frequency range. Our idea

Constant-pressure sound waves in non-Hermitian disordered media

When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions of a wave’s free propagation is a challenging task

Anomalous Anderson localization behavior in gain-loss balanced non-Hermitian systems

Abstract It has been shown recently that the backscattering of wave propagation in one-dimensional disordered media can be entirely suppressed for normal incidence by adding sample-specific gain and

Observation of photonic constant-intensity waves and induced transparency in tailored non-Hermitian lattices

Light propagation is strongly affected by scattering due to imperfections in the complex medium. It has been recently theoretically predicted that a scattering-free transport through an inhomogeneous

We investigate the propagation of Gaussian beams through optical waveguide lattices characterized by correlated non-Hermitian disorder. In the framework of coupled mode theory, we demonstrate how the

Equal-intensity waves in non-Hermitian media.

A novel type of waves is examined in the context of non-Hermitian photonics that support localized paraxial solutions whose intensity distribution is exactly the same as the intensity of a corresponding solution in homogeneous media.

Nonlinear scattering by non-Hermitian multilayers with saturation effects.

It is shown that by tuning the parameters of the layers the authors can effectively control the impact of nonlinearity on the scattering characteristics of the non-Hermitian layered structure.

Broadband perfect transmission through non-Hermitian disordered media

We examine the resonance properties of a novel type of waves, the constant-intensity (CI) waves in one-dimensional non-Hermitian disordered media. Such CI waves propagate perfectly through a



Generating particlelike scattering states in wave transport.

This work introduces a procedure to generate scattering states which display trajectorylike wave function patterns in wave transport through complex scatterers and pave the way for the experimental realization of highly collimated wave fronts in transport throughcomplex media with possible applications such as secure and low-power communication.

Measuring the transmission matrix in optics: an approach to the study and control of light propagation in disordered media.

The transmission matrix of a thick random scattering sample is determined and it is shown that this matrix exhibits statistical properties in good agreement with random matrix theory and allows light focusing and imaging through the random medium.

Constant-intensity waves and their modulation instability in non-Hermitian potentials.

A whole class of waves that have constant intensity in the presence of linear as well as of nonlinear inhomogeneous media with gain and loss are presented to study the fundamental phenomenon of modulation instability in an inhomogeneity environment.

The single-channel regime of transport through random media

It is demonstrated that in deeply localized quasi-1D systems, the single dominant transmission eigenchannel is formed by an individual Anderson-localized mode or by a ‘necklace state’.

Spatio-temporal focusing of an ultrafast pulse through a multiply scattering medium.

This approach shows that a multiply scattering medium can be put to profit for light manipulation at the femtosecond scale, and has a diverse range of potential applications that includes quantum control, biological imaging and photonics.

Controlling waves in space and time for imaging and focusing in complex media

In complex media such as white paint and biological tissue, light encounters nanoscale refractive-index inhomogeneities that cause multiple scattering. Such scattering is usually seen as an

Transport through modes in random media

It is shown that the field speckle pattern of transmitted radiation can be decomposed into a sum of the patterns of the individual modes of the medium and the central frequency and linewidth of each mode can be found, which allows to explain complexities of steady state and pulsed transmission of localized waves and to harmonize wave and particle descriptions of diffusion.

Light fields in complex media: Mesoscopic scattering meets wave control

Wave front shaping, the ability to manipulate light fields both spatially and temporally, in complex media is an emerging field with many applications. This review summarizes how insights from

Engineering of light confinement in strongly scattering disordered media.

The possibility to engineer the confinement and the mutual interaction of modes in a two-dimensional disordered photonic structure is experimentally demonstrated and selectively control the detuning between overlapping localized modes and observe both frequency crossing and anti-crossing behaviours, paving the way for the creation of open transmission channels in strongly scattering media.

Anderson localization and nonlinearity in one-dimensional disordered photonic lattices.

An intermediate regime is found in which the ballistic and localized components coexist while diffusive dynamics is absent and evidence is found for a faster transition into localization under nonlinear conditions.
