Advanced liquid crystal-based light engines and planar optical components play pivotal roles for systematically improving the image quality and formfactor of the augmented reality and virtual reality displays.

All-optical computation of a group of linear transforms is achieved using a polarization-encoded diffractive optical processor.

We generate extremely asymmetric sub-half-cycle terahertz waveforms with scalable field strengths at megahertz pulse-repetition rates via ultrafast excitation of spatially indirect interband transitions in tailored quantum well heterostructures.

The shield and black wire symbolize two layers necessary for passive radiative cooling. The first protects from solar radiation, the second connects to Space functioning as a heat sink.

Label-free rapid deep-learning-based identification of bacterial species that classifies 3D refractive index tomograms into the species.

A tunable liquid crystal grating-based holographic 3D display system is proposed with wide viewing angle and large size.

Chaotic output of a self-chaotic microlaser with the typical wide lasing spectra, as shown, was applied for high speed random number generation.

The image depicts a schematic illustration of a van der Waals heterostructure used to electrically activate quantum emitters in hexagonal boron nitride.

Efficient blue-light excited cyan-emitting persistent luminescence phosphor BaLu₂Al₂Ga₂SiO₁₂:Ce³⁺, Bi³⁺ is designed and synthesized to effectively compensate for the flicker effect of AC LEDs.
