Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

Abstract: The current fundamental limits such as Shockley–Queisser, ergodic light-trapping limit, diffraction-limited imaging (Abbe diffraction limit), noise in detection, reciprocal optical systems ...

(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...

A technical paper titled “Scalable nanopatterning of organic light-emitting diodes beyond the diffraction limit” was published by researchers at ETH Zurich, University of Alberta, Indian Institute of ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
