Enforcing Levy relaxation for multi-mode fibers with correlated disorder
Yaxin Li, Doron Cohen, Tsampikos Kottos
Environmental perturbations and noise are source of mode mixing and interferences between the propagating modes of a complex multi-mode fiber. Typically, they are characterized by…
Perfect Absorption in Complex Scattering Systems with or without Hidden Symmetries
Lei Chen, Tsampikos Kottos, Steven M. Anlage
Wavefront shaping (WFS) schemes for efficient energy deposition in weakly lossy targets is an ongoing challenge for many classical wave technologies relevant to next-generation tel…
Optical Phase Transitions in Photonic Networks: A Spin System Formulation
Alba Ramos, Tsampikos Kottos, Boris Shapiro
We investigate the collective dynamics of nonlinearly interacting modes in multimode photonic settings with long-range couplings. To this end, we have established a connection with…
Coherent Wave Propagation in Multi-Mode systems with Correlated Noise
Yaxin Li, Doron Cohen, Tsampikos Kottos
Imperfections in multimode systems lead to mode-mixing and interferences between propagating modes. Such disorder is typically characterized by a finite correlation time (in quantu…
Statistical Design of Chaotic Waveforms with Enhanced Targeting Capabilities
Huanan Li, Suwun Suwunnarat, Tsampikos Kottos
We develop a statistical theory of waveform shaping of incident waves that aim to efficiently deliver energy at weakly lossy targets which are embedded inside chaotic enclosures. O…
Random Matrix Theory Approach to Chaotic Coherent Perfect Absorbers
Huanan Li, Suwun Suwunnarat, Ragnar Fleischmann +2
We employ Random Matrix Theory in order to investigate coherent perfect absorption (CPA) in lossy systems with complex internal dynamics. The loss strength and energy…
