Abstract

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.

Not Every Exit is an Entrance

Published 16 July 2012

Experiments demonstrate a new way to prevent light from retracing its steps, which could potentially be integrated with other components on a chip to process optical information.
