A new semipolar InGaN LED with an integrated metasurface produces circularly polarized light at 68% conversion efficiency, ...

A new publication from Opto-Electronic Technology; DOI 10.29026/oet.2026.260001 , discusses empowering next-generation photodetectors through ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

New LEDs structure reduces energy loss and enables compact light sources for AR/VR, 3D displays, and quantum ...

A research team has demonstrated the first nonlinear metasurface with engineered nonlocality, that simultaneously delivers high‑Q resonance enhancement and pixel‑level control of the wavefront of ...

Holography-the science of recording and reconstructing light fields-has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can ...
