Thin, simple diffractive lenses are notorious for their blurry images, so they have never been used in astronomical observatories. But if you could improve their clarity, using diffractive lenses ...

Spatially incoherent diffractive optical processors can handle data beyond non-negative values, potentially making them valuable in diverse scenarios, such as visual encryption and autonomous vehicle ...

All-optical image denoising using diffractive visual processors. Credit: Ozcan Lab UCLA While image denoising algorithms have undergone extensive research and advancements in the past decades, ...

In today’s digital age, computational tasks have become increasingly complex. This, in turn, has led to an exponential growth in the power consumed by digital computers. Thus, it is necessary to ...

As photonics continues to penetrate the world of consumer electronics and telecommunications, there is an increasing need for custom-designed optical parts that are low cost, compact and lightweight.

A project to develop diffractive solar sails has advanced to the third and final phase of NASA’s advanced concepts program. The team behind the project now has two years to further develop this ...

A broad range of optical devices use nanostructured layers and surfaces to manipulate beams of light through diffraction and interference. Example devices include diffraction gratings, metasurfaces, ...

State-of-the-art neural networks depend on linear operations, such as matrix-vector multiplications and convolutions. While dedicated processors like GPUs and TPUs exist for these operations, they ...
