Giant on-chip non-reciprocity and gyration through synthetic fields in modulated LiNbO3 ring resonators

Abstract

We experimentally realize a photonic gauge potential in an electro-optically modulated LiNbO3 nanophotonic resonator chain. We show that the induced synthetic fields can be adjusted to produce as much as 60 dB non-reciprocal contrast for light transmission and additionally can achieve optical gyration.
