  • Nonreciprocal components are widely used in optical circuits but the magneto-optic effects they are based on pose difficulties for on-chip integration. Here, Ruesink et al. propose an optomechanical scheme to break reciprocity without the need for magnetic fields.

  • 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.
