Abstract
Here, we demonstrate that low-symmetry three-dimensional conductive materials with large Berry curvatures (e.g., doped trigonal tellurium) under a static electric bias may behave as “distributed transistors” and provide polarization-tunable nonreciprocal and non-Hermitian responses. It is shown that doped tellurium offers a non-Hermitian linear electrooptic response that may enable realizing electromagnetic isolators, as well as achieving circular dichroism, and importantly, optical gain.
