Ten years into the future. That's about how far UC Santa Barbara electrical and computer engineering professor John Bowers and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It's technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and network hardware products to come, but do so with high stability, low noise and the energy efficiency of silicon photonics.

Hyperbolic metamaterials are artificially made structures that can be formed by depositing alternating thin layers of a conductor such as silver or graphene onto a substrate. One of their special abilities is supporting the propagation of a very narrow light beam, which can be generated by placing a nanoparticle on its top surface and illuminating it with a laser beam.

Electronics rely on the movement of negatively-charged electrons. Physicists strive to understand the forces that push these particles into motion, with the goal of harnessing their power in new technologies. Quantum computers, for instance, employ a fleet of precisely controlled electrons to take on goliath computational tasks. Recently, researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) demonstrated how microwaves cut in on the movements of electrons. The findings may contribute to future quantum computing technology.

Electrons flowing across the boundary between two materials are the foundation of many key technologies, from flash memories to batteries and solar cells. Now researchers have directly observed and clocked these tiny cross-border movements for the first time, watching as electrons raced seven-tenths of a nanometer – about the width of seven hydrogen atoms – in 100 millionths of a billionth of a second.

A new analysis has revealed that advanced satellite-based instrument capabilities are needed for global monitoring of microscopic particles, or aerosols, in the stratospheric layer of the atmosphere. Aerosols in the stratosphere—located above approximately 12 kilometers—increase drastically after a volcanic eruption, leading to changes in the Earth's climate and providing a critical opportunity to test scientific models designed to predict short- and long-term climate variations.

Lasers are widely used in household appliances, medicine, industry, telecommunications and more. Several years ago, scientists introduced nanolasers. Their design is similar to that of the conventional semiconductor lasers based on heterostructures in common use for several decades. The difference is that the cavities of nanolasers are exceedingly small, on the order of the wavelength of the light they emit. Since they mostly generate visible and infrared light, the size is on the order of one millionth of a meter.

Sometimes, opportunities fall into our laps when we're least expecting them. A team of CERN surveyors, in collaboration with the Institute of Plasma Physics in Prague (IPP), has developed a pioneering laser beam while working on a particularly challenging alignment system. "While developing the alignment system for the HIE-ISOLDE accelerator, we discovered that the system generating a structured laser beam had astonishing optical properties", explain Jean-Christophe Gayde (CERN, EN-SMM-ESA) and Miroslav Šulc (IPP), the system's inventors. "We didn't initially plan to develop a generator for this kind of laser beam, but the results of our research were very encouraging."

Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. The technique uses interferometry; in which light reflected from an examined object combines with reference light that does not encounter the object to generate interference patterns that form 2-D and 3-D OCT images. It is possible to use longer wavelengths of light in the imaging technique for deeper penetration in light scattering materials. Such features offer possibilities for OCT in non-destructive testing (NDT) of samples, and improved non-invasive biomedical imaging. In a recent study, Niels M. Israelsen and co-workers at the Technical University of Denmark, together with collaborators in Austria and the U.K., developed a new method to overcome the technical challenges of OCT imaging.

Electrons inside an atom whip around the nucleus like satellites around the Earth, occupying orbits determined by quantum physics. Light can boost an electron to a different, more energetic orbit, but that high doesn't last forever. At some point the excited electron will relax back to its original orbit, causing the atom to spontaneously emit light that scientists call fluorescence.

Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of its linewidth, or coherence, which is the ability to emit a constant frequency over a certain period of time before that frequency changes.
