N2 - It is shown how time-modulating the refractive index of two coupled microcavities with a 90 degree phase shift between them leads to non-reciprocal wave propagation. The cavities are implemented as defects in a one-dimensional photonic crystal. The ratio of forward to backward power transmission can be as high as 25 dB with experimentally realizable modulation frequencies and amplitudes. Further, it is demonstrated how a simple passive filter can remove modulation sidebands.
