We demonstrate polarization encoding of upconverted light with orthogonal polarization states into opposite diffraction orders of a metasurface, enabling all-optical tuning between linear and circular polarization by adjusting the pump pulse phase delay.

This work presents a scalable on-chip optical neural network leveraging partially coherent sources for real-valued computing and wavelength-multiplexed parallelism, enhancing accessibility and integration potential.

Micro-LEDs will lead next-generation display technology such as transparent, deformable and near-eye displays, enabling a wide range of applications with superior performance.

This study reveals the triboluminescence (TL) phenomenon of the metal halide perovskite film for the first time, which is based on a new mechanism of friction-induced lattice stretching, significantly distinct from that of the conventional TL.

We detect the continuous variable entanglement by a measurement-device-independent entanglement witness in a quantum network. Our results provide a trustworthy method of entanglement detection for constructing secure quantum networks.

This work reports on a new concept of time-resolved photon counting Fourier-transform micro-spectroscopy, allowing continuous scanning by converting photon arrival times to interferometer position.

Transition from one bound state in the continuum to exceptional ring and optical-pump-controlled such exceptional point switching demonstrated in terahertz metasurfaces.

The first experimental demonstration of extreme ultraviolet (XUV) plasmon-enhanced self-driven spectral modification using a submicrometric foil of aluminium. These findings mark a breakthrough in enhancing XUV nonlinearities.
