We propose an efficient mode management scheme in active nonlinear multimode fibers based on non-Hermitian potentials in the longitudinal direction with an antisymmetric transverse profile. The proposal takes advantage of the nonlinear saturation tow

We provide a feasible and compact scheme to control and stabilize the spatiotemporal dynamics of BAS lasers. The proposal is based on the ability of non-Hermitian potentials with given local symmetries to manage the flow of light. A local PT-symmetri

We show an efficient mechanism to control optical turbulence in systems with different dispersion laws, including parabolic, sub-diffractive, hyper-diffractive or general fractional dispersion. The method is based on the modification of the energy ca

We uncover new families of stable periodic solutions by the introduction of non-Hermitian potentials in the universal complex Ginzburg–Landau equation. We perform a comprehensive analysis on the dynamics and stability of the system by determining a

We propose a method for a control of turbulence by modifying the excitation cascade leading to turbulence. The method is based on the asymmetric coupling between the spatiotemporal excitation modes by non-Hermitian potentials. The non-Hermitian poten

In this paper, we propose a general inverse-design strategy based on genetic algorithm optimization to achieve ‘on demand’ manipulation of light in one-dimensional (1D) and two-dimensional (2D) non-Hermitian systems. The optimization process fait

We introduce a new method to affect the energy cascade through wavevectors accountable for the turbulence. By the introduction of a spatiotemporal non-Hermitian potential we have been able to tilt or promote the energy cascade to reduce or increase t
