Optical turbulence control by non-Hermitian potentials

We propose a method for control of turbulence by modifying the excitation cascade leading to turbulence. The is based on asymmetric coupling between spatiotemporal modes non-Hermitian potentials. potentials are recently known enable unidirectional modes. demonstrate that such towards larger (smaller) wave numbers can increase (reduce) energy flow in turbulent states, and therefore, influence character study complex Ginzburg-Landau equation, universal model pattern formation wide range systems including nonlinear optical resonators. show enhancement or reduction indeed dependent imposed direction flow, controlled phase shift real imaginary parts temporal oscillation potential.
