Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables.

How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access ...

A single gold nanorod, far smaller than a wavelength of visible light, can be coaxed into emitting circularly polarized ...

Researchers in Singapore have developed fully vacuum-processed ultrathin perovskite solar cells with absorber layers as thin as 10 nm, achieving high transparency and stable efficiencies up to 12%.

Recent advances in optical methods for biological sample characterization reflect a profound shift driven by the convergence of photonic innovation, computational intelligence, and increasing ...

Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an especially impressive impact on science and technology. Now, researchers in ...

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 ...

Layered metasurfaces trained as optical neural networks enable multifunctional holograms and security features, integrating neural computation principles with nanostructured optics to create a ...

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 ...

Microscopy with extreme ultraviolet (EUV) radiation enables high-resolution imaging with excellent material contrast because of the short wavelength and numerous element-specific absorption edges ...
