We introduce special states for light in multimode waveguides featuring strongly enhanced or reduced spectral correlations in the presence of strong mode coupling. Based on the experimentally measured multispectral transmission matrix of a multimode

PT-symmetric scattering systems with balanced gain and loss can undergo a symmetry-breaking transition in which the eigenvalues of the nonunitary scattering matrix change their phase shifts from real to complex values. We relate the PT-symmetry-break

Significance In the presence of a weakly fluctuating potential landscape, waves exhibit pronounced enhancements along so-called “branches.” The formation of these beautiful branches is a universal phenomenon occurring on vastly different length s

Non-Hermitian wave engineering is a recent and fast-moving field that examines both fundamental and application-oriented phenomena1–7. One such phenomenon is coherent perfect absorption8–11—an effect commonly referred to as ‘anti-lasing’ be

The central goal in optical wave control is to manipulate light fields so that they fulfil a certain function, such as for imaging, detection and efficient transmission across complex photonic media. To reach this goal, different techniques have been

We realize scattering states in a lossy and chaotic two-dimensional microwave cavity which follow bundles of classical particle trajectories. To generate such particlelike scattering states, we measure the system's complex transmission matrix and app

We introduce a wave front shaping protocol based on a generalization of the Wigner-Smith time-delay operator. This tool is used to create light fields with desired properties at a predetermined target embedded inside a medium.

Optical pulses propagating through a multimode fiber with random mode mixing experience temporal broadening and distortion. Principal modes have been proposed to overcome modal dispersion. They are the eigenstates of the time delay operator and the a

We experimentally generate principal modes in a multimode fiber with strong mode coupling. They possess unique spectral and temporal properties. We reveal that principal modes are formed by multi-path interference effect, which is manipulated by the
