NONLINEAR PHOTONICS

Low-loss nonlinear optical isolators in silicon

Nature Photonics volume 14, pages 338–339 (2020)Cite this article

Subjects

Asymmetric forward and backward transmission through photonic structures can be achieved via optical nonlinearities, but existing systems have typically used slow thermo-optic effects. A new resonator design has now enabled low-loss, non-reciprocal pulse routing based on the Kerr nonlinearity in integrated silicon waveguides.
