Crosstalk‐Mitigated OAM Recovery Through Strong Scattering via Sparsity‐Regularized LG‐TM

Guangdong Ma, Shupeng Zhao, Xiao Wang, Min An et autres

ABSTRACT Light beams carrying orbital angular momentum (OAM) provide an unbounded set of mutually orthogonal spatial modes, enabling high‐dimensional information encoding for optical communication and sensing. However, strong scattering severely distorts the helical phase structure of OAM beams, introducing inter‐modal crosstalk that …

Compressive single-pixel imaging via a wavelength-multiplexed spatially incoherent diffractive optical processor

Xiao Wang, Yiyang Wu, Yuntian Wang, Md Sadman Sakib Rahman et autres

Despite offering high sensitivity, a high signal-to-noise ratio, and a broad spectral range, single-pixel imaging (SPI) is limited by low measurement efficiency and long data-acquisition times. To address this, we propose a wavelength-multiplexed, spatially incoherent diffractive optical processor combined with a compact/shallow …

High-fidelity orbital angular momentum spectrum reconstruction via sparse intensity measurements

Xiao Wang, Guangdong Ma, Yongtao Zhao, Pei Zhang et autres

Accurate reconstruction of the complex spectrum of orbital angular momentum (OAM) superposition states is crucial for their application in high-capacity optical communications and quantum information, yet existing methods are often constrained by system complexity, extensive data requirements, or incomplete information retrieval. Here, …

Multiplexed large-scale permutation operations using a reconfigurable diffractive optical network

Guangdong Ma, Xilin Yang, Bijie Bai, Jingxi Li et autres

We report a reconfigurable multiplexed diffractive processor that utilizes diffractive layer rotations to all-optically execute a large set of high-dimensional permutation operations. Within this rotatable diffractive design, each diffractive layer permits four independent rotation angles at 0°, 90°, 180°, and 270°. Therefore, …

Unidirectional visual processor with partially coherent illumination

Guangdong Ma, Che‐Yung Shen, Jingxi Li, Luzhe Huang et autres

We demonstrate a polarization-independent unidirectional visual processor with partially coherent illumination that achieves image formation in the forward direction (A→B) while blocking the image formation in the reverse direction (B→A).
