Abstract
Here, we demonstrate that low-symmetry two-dimensional metallic systems with large Berry curvature dipoles biased with a static electric field may behave as “distributed transistors” and provide polarization-tunable non-Hermitian and non-reciprocal responses. It is shown that an incident electromagnetic wave passing through the biased two-dimensional material may experience optical gain, depending on the wave polarization, direction of wave propagation, and orientation of the electric bias.
