A career in optical physics or engineering means knowing about the behavior and properties of light, including its interactions with matter and its detection by instruments. Since the discovery that ...

High-accuracy determination of the position of features in the field of view (positioning) is one of the most significant functions of a camera used on a satellite. Knowledge of the inner orientation ...

Geometrical optics, a branch of optics that eschews wave phenomena in favour of ray propagation, continues to underpin advances in lens design and optical engineering. Contemporary studies in this ...

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

(Nanowerk Spotlight) The simplest way to trap light, or in general electromagnetic waves, in a finite region is to realize a region surrounded by mirrors so that light is not able to escape. The ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase route ...

Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...

Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...
