Researchers Demonstrate Novel Quantum Dot Laser Grown on Silicon Substrates

With the explosive growth of bandwidth demand in telecommunications networks, experts are continually seeking new ways to transmit increasingly large amounts of data in the quickest and cheapest ways possible. Photonic devices—which convert light to electricity and vice versa—offer an energy-efficient alternative to traditional copper network links for information transmission. Unfortunately, these devices are also almost always prohibitively pricey.

Scientists Observe Polarization of a Photon Emitted in Weak Decay of a Bottom Quark

As members of the LHCb collaboration, scientists at EPFL have analyzed data collected at CERN’s Large Hadron Collider that offer a first-time observation of the polarization of the photon emitted in the weak decay of a bottom quark. This finding opens the way to future measurements, which may reveal a reality deeper than the one described by the present theory of elementary particles, the so-called Standard Model.

Femtosecond Lasers can be used Without Sophisticated Stabilization Schemes

A team of scientists around Dr. Nathalie Picqué and Prof. Theodor W. Hänsch at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics (Garching), in a collaboration with the Ludwig-Maximilians-Universität Munich and the Institut des Sciences Moléculaires d’Orsay (France) now reports on a new method of real-time identification and quantification of molecular species (Nature Communications 5, 3375 – Feb. 27, 2014).

Spitzer Peers into the Heart of Stellar Explosion in the ‘Cigar Galaxy’

The closest supernova of its kind to be observed in the last few decades has sparked a global observing campaign involving legions of instruments on the ground and in space, including NASA's Spitzer Space Telescope. With its dust-piercing infrared vision, Spitzer brings an important perspective to this effort by peering directly into the heart of the aftermath of the stellar explosion.
