Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major ...

For any disordered medium (such as a sugar cube, for example), special light waves can be found which are practically not changed by the medium, only attenuated. These 'scattering invariant light ...

In the dynamic realm of optical physics, researchers are continually pushing the boundaries of how light can be manipulated and harnessed for practical applications. As reported in Advanced Photonics ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

...and succeeds in medical diagnostic imaging without image reconstruction for the first time in the world. iPMSEL array on a fingertip; and impressions of light sources DOE, VCSEL, and iPMSEL.
