Suppression and restoration of disorder-induced light localization mediated by PT-symmetry breaking
Yaroslav V. Kartashov, Chao Hang, Vladimir V. Konotop +3
We uncover that the breaking point of the PT-symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, wh…
Efficient mode conversion in guiding structures with longitudinal modulation of nonlinearity
Victor A. Vysloukh, Yaroslav V. Kartashov, Kestutis Staliunas
We describe power-dependent dynamics of conversion of the guided modes of various guiding structures due to nearly resonant longitudinal modulation of the nonlinear coefficient of…
Dynamic versus Anderson wavepacket localization
Olga V. Borovkova, Valery E. Lobanov, Yaroslav V. Kartashov +2
We address the interplay between two fundamentally different wavepacket localization mechanisms, namely resonant dynamic localization due to collapse of quasi-energy bands in perio…
