The proposed visual remote sensing platform utilizes geometric phase encoding of stimuli-responsive cholesteric liquid crystal polymers to generate intuitive image signals, showcasing its proof of concept by real-time humidity monitoring.
Operando monitoring of mass transport kinetics and lithium dendrite growth in lithium metal batteries and parametrization of the batteries’ electrochemistry and safety have been achieved using optical fiber sensors.
We achieve the first deterministic coupling of a topological corner state with a single quantum dot, observing Purcell enhancement and polarized single-photon emission. This extends the effect of higher-order topological phase into the quantum realm.
The Yb3+ emissions from both the quantum cutting and nearly-pure infrared upconversion and excellent temperature detection were realized in Er3+/Yb3+ co-doped NaY(WO4)2 phosphors.
A van der Waals complex with an internuclear distance of 0.39 nm is designed as a prototype system to track electron tunneling via neighboring atoms within a sub-nanometer scale.
A real-time photonic chip with fully integrated signal processing path and co-packaged electronics can effectively address dynamic RF interference with picosecond latency, benefiting applications like telecommunications and transportation.
We showcase the use of deep diffractive neural networks to construct a series of high fidelity and high-dimensional quantum gates, which are encoded by the spatial modes of photons.
Ultra-simplified compact spectrometer with a simple, arbitrarily shaped pinhole as the diffracted disperser, eliminating need for encoding and full spectrum calibration, and achieving better than 3 nm spectral peak resolution.
We demonstrate cavity-enhanced photoacoustic dual-comb spectroscopy with a flute-type acoustic resonator and an optical cavity for spectral measurements with ultra-high sensitivity, high resolution, and broad bandwidth.
Single-molecule fluorescence lifetime imaging microscopy (smFLIM) measures the radiative decay rate of single molecules in the near field of dielectric nanoantennas providing super-resolved information of the local density of states.
We developed a novel label-free plasmonic biosensing configuration for sub-femtomolar (10−16 M) small molecule detection with an ultra-high sensitivity of 1.72 × 108 nm RIU−1 and a large figure of merit (FOM).
Self-hybridized exciton–polaritons are shown to enable sub-bandgap absorption and emission in 2D perovskites. The energy absorbed by the perovskites are also found to transfer to few-layer graphene in a heterostructure.
