OPTOELECTRONIC DEVICES

On-chip non-magnetic optical isolator

Nature Photonics volume 15, pages 794–795 (2021)Cite this article

Subjects

Practical on-chip optical isolators providing non-reciprocal propagation are still a challenge. Now, two independent groups show that a phonon-mediated break of the chiral symmetry in waveguide resonators may offer a solution.
