A rigid, low-loss fiber-optic coupler for cryogenic photonics
Mengdi Zhao, Kejie Fang
Recent developments in quantum light-matter coupled systems and quantum transducers have highlighted the need for cryogenic optical measurements. In this study, we present a mechan…
Observation of photon-phonon correlations via dissipative filtering
Mengdi Zhao, Kejie Fang
Cavity-optomechanics enables photon-phonon interaction and correlations by harnessing the radiation-pressure force. Here, we realize a ``cavity-in-a-membrane'' optomechanical archi…
Optomechanical crystal with bound states in the continuum
Shengyan Liu, Hao Tong, Kejie Fang
Chipscale micro- and nano-optomechanical systems, hinging on the intangible radiation-pressure force, have shown their unique strength in sensing, signal transduction, and explorat…
InGaP quantum nanophotonic integrated circuits with 1.5% nonlinearity-to-loss ratio
Mengdi Zhao, Kejie Fang
Optical nonlinearity plays a pivotal role in quantum information processing using photons, from heralded single-photon sources, coherent wavelength conversion to long-sought quantu…
Mechanical bound states in the continuum for macroscopic optomechanics
Mengdi Zhao, Kejie Fang
Bound states in the continuum (BICs), an emerging type of long-lived resonances different from the cavity-based ones, have been explored in several classical systems, including pho…
Anomalous quantum Hall effect of light in Bloch-wave modulated photonic crystals
Kejie Fang, Yunkai Wang
Effective magnetic fields have enabled unprecedented manipulation of neutral particles including photons. In most studied cases, the effective gauge fields are defined through the…
