Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion ...

Lithium niobate (LN) powers a newly developed optical metasurface for shaping and guiding light waves. Leveraging the electro-optical effect of lithium niobate, the device applies different electric ...

Scattering of light as it passes through tissue is a significant barrier to imaging cleanly in biological media such as blood and skin. Wavefront shaping (WFS) is known to be a possible solution, in ...

Researchers in Caltech's Andrew and Peggy Cherng Department of Medical Engineering have made what they call "a major step forward in medical imaging" by taking inspiration from the field of astronomy.

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

As anyone who has recently tried out an augmented reality headset knows, the technology is not yet ready to be part of our everyday lives. Researchers have been working to perfect high-performing ...

Adaptive optics is a class of components that can be added to optical systems to improve their performance. They do this by reducing the incoming wave distortions which can arise due to natural ...

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Reported in ...

Metasurfaces and metalenses are advancing high-resolution imaging, providing exceptional light control and improving ...
