Optical circulation in a multimode optomechanical resonator

Nonreciprocal optical elements mostly rely on magnetic fields to break time-reversal symmetry, an approach that is difficult to integrate on-chip. Here, Ruesink et al. describe and demonstrate 4-port circulation at telecom wavelengths using a magnetic-field-free optomechanical resonator.
