Photonic modal circulator using temporal refractive-index modulation with spatial inversion symmetry
Jiahui Wang, Jason F. Herrmann, Jeremy D. Witmer +2
It has been demonstrated that dynamic refractive index modulation, which breaks time-reversal symmetry, can be used to create on-chip non-reciprocal photonic devices. In order to a…

Integrated Nonreciprocal Photonic Devices with Dynamic Modulation
Ian A. D. Williamson, Momchil Minkov, Avik Dutt +3
Nonreciprocal components, such as isolators and circulators, are crucial components for photonic systems. In this article we review theoretical and experimental progress towards de…
