Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals
Laser &Photonics Reviews, EarlyView.The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Holography: art with light [PDF]
, 2015 “It’s the intersection of art, science, and technology that makes holography so interesting,” stated Stephen Benton (1941-2003), a key figure in the development of modern holography not only on account of his scientific achievements (such as the ...

Compact Single‐Shot Incoherent Edge Detection With a Polarization‐Multiplexed Metalens
Laser &Photonics Reviews, EarlyView.A polarization‐sensitive metalens enables single‐shot incoherent edge detection by generating two polarization‐dependent images and digitally subtracting them to realize a high‐pass optical transfer function. ABSTRACT Edge detection under incoherent illumination is highly desirable for compact vision systems but remains challenging due to the lack of ...

Reviewing the Inclusion of Artists’ Holograms in the Permanent Collections of Fine Art Museums
Arts, 2019 Opening in 1976 with the exhibition, “Through the Looking Glass”, the Museum of Holography (MOH) emphasized from the beginning the importance of artistic holography with the inclusion of several holograms by artists whose primary practice was

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 ...

Weak Measurement for Characterizing Effective Jones Matrices of Phase Gradient Metasurfaces
Laser &Photonics Reviews, EarlyView.Spin dependent deflection from a PB phase gradient metasurface is converted by two dimensional weak measurement into a centroid map, where the amplitude ratio, phase difference, and phase gradient produce distinct spatial features. These effective parameters are then retrieved directly from the centroid response.

Cone holography with Neumann boundary conditions and brane-localized gauge fields
Journal of High Energy PhysicsCone holography is a codimension-n doubly holographic model, which can be interpreted as the holographic dual of edge modes on defects. The initial model of cone holography is based on mixed boundary conditions. This paper formulates cone holography with

Small, EarlyView.Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

Recent progress of atomic resolution holography: from point defects to defect complexes
Applied Physics ExpressAtomic-resolution holography, which uses X-rays or neutrons with wavelengths of about 1 Å, is a technique for visualizing three-dimensional local structures around specific elements, and its variations were demonstrated between 1990 and 2001 ...
