What Do Forbidden Light-ray Fields Look Like? [PDF]
, 2014 Ray-optically, optical components change a light-ray field on a surface immediately in front of the component into a different light-ray field on a surface behind the component.

All-Dielectric Meta-Surface for Multispectral Photography by Theta Modulation
Nanomaterials, 2020 The traditional theta modulator encodes input information by superimposing Ronchi sub-gratings, which is extremely easy to cause spatial channel overlap that results in bands mixing.

Resilient Calcination Transformed Micro-Optics
HMAM2, 2023 Three-dimensional multiphoton laser lithography of hybrid resins has been shown to be a viable tool for producing micro-optical functional components. The use of calcination heat treatment also allows the transformation of such structures from the initial polymer to final glass and glass-ceramic. Although the laser-induced damage threshold (LIDT) is an
