Every wireless router in a home or office broadcasts the same fundamental type of energy that a ceiling light emits. The ...

That’s according to Jonathan P. How, describing the breakthrough that has pushed insect-scale aerial robots into a new ...

A depth-compensated diffractive optical element photoacoustic microscope enables more uniform photoacoustic imaging across tissue depths.

A research team led by The Chinese University of Hong Kong (CUHK) has developed a novel integrated all-optical signal processor (OSP) to address the massive data transmission demands of ...

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...

Beyond the use of optical frequency combs as precision clock sources in the optical region, researchers have developed a way ...

Arrays of resonant nanoparticles, so-called metasurfaces, have been developed and demonstrated as the first generation of meta-operators. Unlike today’s electronic systems, the demonstrated compact, ...

Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent ...

Optical neural networks promise unmatched efficiency, bandwidth, and latency — critical benefits as demand for neural network hardware surges. However, their practical value for general-purpose ...
