UCLA researchers introduced an innovative design for diffractive deep neural networks (D2NNs). This new architecture, termed Pyramid-D2NN (P-D2NN), achieves unidirectional image magnification and demagnification, significantly reducing the number of diffractive features required.

High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions
The emerging mono-elemental tellurium nanofilms with unique helical chain structure have been introduced as a new class of optically controlled terahertz modulators to successfully promote the device performances to the optimal levels among the existing all two-dimensional broadband modulators.
