The authors demonstrate the enhancement of nonlinear optomechanical measurement of mechanical motion by using pairs of coupled optical and mechanical modes in a 1D photonic crystal. The design harnesses the anisotropic mechanical elasticity to create

Abstract Topological on-chip photonics based on tailored photonic crystals (PhCs) that emulate quantum valley-Hall effects has recently gained widespread interest owing to its promise of robust unidirectional transport of classical and quantum inform

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 magneti

Fully integratable spectrometers have trade-offs between size and resolution. Here, the authors present a nano-opto-electro-mechanical system where the functionalities of transduction, actuation and detection are fully integrated, resulting in an ult

Optomechanical experiments often assume linear coupling between optical fluctuations and mechanical displacements. Here, Leijssenet al. experimentally demonstrate the nonlinear interaction from thermally induced fluctuations in a sliced nanobeam cavi

The fields of cavity optomechanics and Brillouin scattering, linked by common underlying physical mechanisms, involve the interaction of light waves with mechanical vibrations at the micro- and nanoscale. Exciting fundamental research in both classic

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 ma

In cavity optomechanics, nonlinear interactions between an optical field and a mechanical resonator mode enable a variety of unique effects in classical and quantum measurement and information processing. Here, we describe nonlinear optomechanical co

It is well known that the quasinormal modes (or resonant states) of photonic structures can be associated with the poles of the scattering matrix of the system in the complex-frequency plane. In this work, the inverse problem, i.e., the reconstructio

Imposing chirality on a physical system engenders unconventional energy flow and responses, such as the Aharonov-Bohm effect and the topological quantum Hall phase for electrons in a symmetry-breaking magnetic field. Recently, great interest has aris
