Electrically Driven Nonreciprocity Induced by Interband Photonic Transition on a Silicon Chip

This is the authors' abstract. We don't add key points for this paper.

We demonstrate electrically driven nonreciprocity on a silicon chip. By achieving an indirect interband photonic transition, we show that the transmission coefficients between two single-mode waveguides become dependent on the propagation directions only in the presence of the electrical drive. Our structure is characterized by a nonsymmetric scattering matrix identical to a linear magneto-optical device.
