Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing ...

A new plasmonic fiber probe uses linearly polarized light and energy recycling for broadband nanofocusing with resolution ...

The rapid evolution of diffractive optical elements (DOEs) is reshaping space telescope design by offering lightweight, compact and high-performance alternatives to conventional optical systems. These ...

Please provide your email address to receive an email when new articles are posted on . Twelve years ago at the AECOS meeting, a program chair asked the audience if in 10 years we would be able to ...

Diffraction is a classic optical phenomenon accounting for the light propagation. The efficient calculation of diffraction is of significant value towards the real-time prediction of light fields. The ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

The total amount of data generated worldwide is expected to reach 175 ZB (Zettabytes; 1 ZB equals 1 billion Terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the disk stack would be 23 times ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

Spectrogon manufactures optical interference filters, thin film coatings, and holographic diffraction gratings. The filters are used in several applications such as medical, process industry, thermal ...
