Laser &Photonics Reviews, EarlyView.Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

Misalignment‐Robust Dynamic Cascaded Holography Accelerated by Deep Neural Networks
Laser &Photonics Reviews, EarlyView.Cascaded holography has mainly been studied using metasurfaces. Here, we demonstrate a fully dynamic cascaded holographic system based on two phase‐only spatial light modulators. A misalignment‐tolerant optimization method preserves image quality despite alignment errors, making cascaded holographic systems simpler, more reliable, and easier to use in ...
