Coupling Enhanced Diffractive Deep Neural Network with Structural Nonlinearity

open access: yesAdvanced Photonics Research, EarlyView.
Here, structural nonlinearity is introduced into diffractive deep neural networks (D2NNs) by incorporating encoding‐free data repetition layers, enabling high‐order optical nonlinearity while reducing the system complexity. Additionally, to enhance the design accuracy of D2NNs, a graph neural network is developed to characterize the coupling effects ...

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review

open access: yesAdvanced Photonics Research, EarlyView.
Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective

open access: yesAdvanced Photonics Research, EarlyView.
This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Advances in Mode (De)Multiplexing Technologies via Circularly Symmetric Structured Light Beams

open access: yesAdvanced Photonics Research, EarlyView.
This review presents a comprehensive overview of mode (de)multiplexing technologies using circularly symmetric structured light beams, encompassing strategies of beam splitter combinations, multiorder diffractive gratings, optical coordinate transformations, angular dispersion lenses, multilayer cascaded modulations, and multidimensional hybrid (de ...

Polynomials, Divided Differences, and Codes

open access: yes
Multivariate multiplicity codes (Kopparty, Saraf, and Yekhanin, J. ACM 2014) are linear codes where the codewords are described by evaluations of multivariate polynomials (with a degree bound) and their derivatives up to a fixed order, on a suitably chosen affine point set.
