Abstract: 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 medium is achievable by non-Hermitian tailoring of the… read more here.

Abstract: Topological constant-intensity (TCI) waves are introduced in the context of non-Hermitian photonics. Unlike other known examples of topological defects, the proposed TCI waves exhibit a counterintuitive behavior because a phase difference occurs across space without… read more here.

DOI: 10.1364/ol.45.000101
Abstract: We engineer anomalous conical diffraction (CD), occurring in discrete one-dimensional lattices with charge-conjugation symmetry when an exceptional point is in the proximity of the modes that compose the initial excitation. The evolving waveform propagates ballistically,… read more here.
