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…
Quantum correlated photons via a passive nonlinear microcavity
Mengdi Zhao, Yunkai Wang, Shanhui Fan +1
Photons, by nature, typically do not exhibit interactions with each other. Creating photon-photon interactions holds immense importance in both fundamental physics and quantum tech…
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…
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…
Observation of phonon trapping in the continuum with topological charges
Hao Tong, Shengyan Liu, Mengdi Zhao +1
Phonon trapping has an immense impact in many areas of science and technology, from the antennas of interferometric gravitational wave detectors to chip-scale quantum micro- and na…
High-efficiency fiber-to-chip interface for aluminum nitride quantum photonics
Mengdi Zhao, Woraprach Kusolthossakul, Kejie Fang
Integrated nonlinear photonic circuits received rapid development in recent years, providing all-optical functionalities enabled by cavity-enhanced photon-photon interaction for cl…
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…
