Full Width at Half Maximum

Flat optics are made of nanostructures containing high-refractive index materials to produce lenses with thin form factors that function only at specific wavelengths.

A new publication in Opto-Electronic Science reports how high-quality diamonds empower narrowband deep ultraviolet photodetection.

An international collaboration of researchers, including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has succeeded in a proof-of-principle experiment to verify strong-field quantum electrodynamics with exotic atoms, by performing high-precision measurements of the energy spectrum of muonic characteristic X-rays emitted from muonic atoms using a state-of-the-art X-ray detector,…

Heat-transport measurements and neutron-scattering spectroscopy probe a form of thermal conduction based on excitations called phasons.

We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV) time series from the ESPRESSO and CARMENES spectrographs. The host star is the quiet M5.5~V star GJ~1002 (relatively faint in the optical, $V \sim 13.8$ mag, but brighter in the infrared, $J \sim 8.3$ mag), located at 4.84 pc from the…

Bose-Einstein condensate of excitons is expected in photo-excited bulk semiconductors, but a direct experimental evidence has been lacking. Here the authors report the observation of a condensate of 1s paraexcitons in Cu2O using real-space mid-infrared absorption imaging realized in a dilution refrigerator.

Radio emission, carrying a wealth of information, is critical for understanding the physical process of various outbursts. The electron cyclotron maser emission (ECME) plays an important role as a coherent radiation mechanism in explaining radio emission phenomena from celestial bodies.

IDEX Health & Science (IH&S) has launched the new Semrock® line of Nanopede™ Optical Filters specifically designed for flow cytometry applications.

The JWST Mid-Infrared Instrument (MIRI) provides imaging and spectroscopic observing modes from 4.9 to 28.8 μm. On this page The JWST Mid-Infrared Instrument

Refractive index—the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum—can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, a new study published in the journal Nanophotonics demonstrates. The study's authors suggest that the ability to sustain PTCs in the optical domain could have profound implications for the science of…

Astronomers generally don't know what happens to planets when their stellar host evolves beyond the main sequence, or whether they can even survive.

One-dimensional semiconductor nanowires with strong quantum confinement effect—quantum wires (QWs)—are of great interest for applications in advanced optoelectronics and photochemical conversions. Beyond the state-of-the-art Cd-containing ones, ZnSe QWs, as a representative heavy-metal-free semiconductor, have shown the utmost potential for next-generation environmental-friendly applications.

A new publication from Opto-Electronic Advances discusses diffraction-limited visible imaging for large aperture telescopes.

From pterodactyls flying overhead in a game to virtually applying cosmetics prior to making a purchase, augmented reality and other immersive technologies are transforming how we play, observe, and learn. Cheap and ultra-small light-emitting diodes (LEDs) that enable full-color imaging at high resolution would help immersive displays reach their full potential, but are not currently available.

Ground-based high-power lasers are, in principle, able to de-orbit any kind of space debris object from the low Earth orbit (LEO) by remotely inducing laser-ablative momentum. However, the assessment of efficiency and operational safety depends on many factors, like atmospheric constraints or the risk of debris disintegration during irradiation. We analyze laser momentum for a great variety of target geometries and…

Organic light-emitting diodes (OLEDs) play an important role in new-generation flat-panel displays. For ultra-high-definition displays presented in International Telecommunication Union (ITU) Recommendation BT 2020 standard, the emitter is required to be high color purity with narrow full width at half-maximum (FWHM).

We demonstrate the ability to receive live color analog television and video game signals with the use of the Rydberg atom receiver. The typical signal expected for traditional 480i National Televi...

On-chip laser diodes based on quantum well (QW) and quantum dot (QD) semiconductor materials have become the primary technology for several applications due to their excellent characteristics, including high power efficiency, high-temperature operation, and small form-factors. Although QWs have been extensively used in commercial products, QDs have emerged as an attractive alternative due to their unique…

There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor tissues can provide multi-dimensional information for the pathological process of cells and human tissues.
