Diffraction gratings are widely used in fields such as precision measurement, laser pulse compression, and spectral analysis. As a maskless lithography method, interference lithography offers high efficiency and flexibility in the fabrication of diffraction gratings. However, the grating size achievable through interference lithography is inherently limited by the aperture of the exposure system’s optical beams, and increasing the aperture of optical elements in the system presents practical cha

Recently, the 2nd China’s Innovation Challenge on Artificial Intelligence Application Scene, co-hosted by the Chinese Association for Artificial Intelligence and New Generation Artificial Intelligence Development Research Center, concluded in Shenzhen.

On February 26, 2025, a groundbreaking papertitled Disorder-assisted real-momentum topological photonic crystalpublished in Natureby Professor Song Qinghuas teamfrom Tsinghua Shenzhen International Graduate School (Tsinghua SIGS). This research introduces a novel concept of real-momentum topological photonic crystals, which can incorporate disorder as information carrier withoutcompromising the topological properties of optical singularities, addressing a significant challenge in the field of to
