Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused ...

The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, ...

Optical materials and structures are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...
