TL;DR: In this article, the authors demonstrate unidirectional monolithically integrated 4×4 optical circulators operating at 1.55 μm on InP. By exploiting the interplay between non-Hermiticity and nonlinearity, an isolation exceeding 20dB was experimentally observed with pulsed inputs.

TL;DR: In this article, a non-reciprocal optical resonator with a small length footprint of 290 µm on a silicon-on-insulator substrate is presented, achieving unidirectional optical transmission with an isolation ratio of up to 19.5 dB near the telecommunications wavelength of 1,550 nm in a homogeneous external magnetic field.

Electrically driven nonreciprocity induced by interband photonic transition on a silicon chip.
TL;DR: By achieving an indirect interband photonic transition, it is shown that the transmission coefficients between two single-mode waveguides become dependent on the propagation directions only in the presence of the electrical drive.

TL;DR: The device, which uses two silicon rings 5 micrometers in radius, is passive yet maintains optical nonreciprocity for a broad range of input power levels, and it performs equally well even if the backward input power is higher than the forward input.
