This work reports a novel nanophotonic platform based on a suspended chalcogenide glass waveguide for on-chip photothermal spectroscopy, enabling highly sensitive near-infrared molecular gas sensing at the parts-per-billion level.

We demonstrated high-speed VCSEL in-memory neural networks that deliver billion optical convolutions per second for massively parallel edge intelligence at ultralow energy and latency.

Polarization-independent Surface Nanostructuring

Low-threshold exciton multiplication in twisted heterobilayers features long-lived interlayer excitons, enhancing emission and photocurrent quantum efficiencies.

Plasmonic nanocavities enable universal detection of layer-breathing modes in two-dimensional materials via plasmon-enhanced Raman spectroscopy, overcoming the limit of weak electron-phonon coupling or Raman inactivity, and delivering a quantitative framework for interlayer coupling analysis.

Two-color pulse compression leveraging quadratic soliton dynamics is demonstrated in a dispersion-engineered lithium niobate nanophotonic waveguide, yielding two-optical-cycle pulses requiring only pJ pump pulse energies.

Very high-brightness, prolonged electrochemiluminescence is achieved by combining an exciplex-formation mechanism with biphasic pulse modulation. Together this enables optogenetic behavioural manipulation and real-time imaging of Drosophila larvae.

Optical coherence microscopy with AI assisted algorithms is used to track organoids and their viability longitudinally. Photoacoustic imaging adds rare cell detection function to the 3D cell culture analysis toolbox.

Inspired by the induced fit theory in molecular biology, this work successfully prepared Ga-based semiconductor films with weak substrate dependence, holding great promise for next-generation electronics and optoelectronics.

We developed flexible, stretchable, on-chip optical tweezers (FSOT) capable of high-throughput trapping and manipulation of bioparticles with sizes ranging from sub-100 nm to tens of micrometers on curved bio-substrates such as skin and intestines.

Recognizing targets in multi-object scenarios, including intra-class, inter-class, and dynamic interference, but not limited to scenarios with multiple interfering objects or spatially overlapping objects by integrating multi-dimensional optical multiplexing technology.

Break-through ASE with ultra-low threshold in Perovskite based on a synergistic dual-regulation strategy leveraging water molecules and additive of BHT.

An anisotropic b-As_0.2P_0.8 phototransistor enables polarization-tunable synaptic behaviors with 4.7 polarization ratio, achieving >90% classification accuracy and high-fidelity polarization imaging through Stokes parameter reconstruction and DoLP mapping.

We report the first experimental demonstration of a topological photonic Dirac vortex mode in terahertz fiber, enabling unprecedented broadband single-mode single-polarization transmission.

By accessing the coherence-collapse regime under strong on-chip feedback, quantum dot lasers demonstrate unprecedented robustness, supporting penalty-free operation and practical isolator-free photonic integrated circuits.

We demonstrated monolithic III–V membrane photonic crystal (PhC) lasers on SOI using selective lateral heteroepitaxy, which enables high mechanical resistance to external impacts and high pumping efficiency within novel fabrication platform of monolithic III–V PhC lasers for Si photonics.
