Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

Advanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View

Advanced Photonics Research, EarlyView.
Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons

Advanced Photonics Research, EarlyView.
Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.

Techniques and Advances in Ultrafast Photography

Advanced Photonics Research, EarlyView.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
