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

The study has been published in the journal Nature Communications. To control light, curved lenses are used today, which are often made of glass that is either concave or convex, which refracts the ...

A research team led by SUTD has created nanoscale glass structures with near-perfect reflectance, overturning long-held assumptions about what low-index materials can do in photonics. For decades, ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...

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 ...

In most filled plastics, mismatches between micron-scale particles and refractive index can cause strong scattering. This shows up on a macroscopic scale as haze and loss of transmittance. When you ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...
