First launched in 1977 as as means to quickly disseminate the latest in optics research and provide the optics and photonics community with a true Letters-style publication, Optics Letters has, over the course of its long history, published influential papers in nonlinear optics, ultrafast spectroscopy, fiber optics, optical communication, and biomedical optics among other areas. This year the Journal celebrates its 40th anniversary and The Optical Society (OSA) has launched a special website to highlight this milestone.
Graphene Flagship research demonstrates large scale, fully integrable arrays of single photon quantum dots in layered materials, which may lead to hybrid on-chip photonics devices for networks and sensing. This method is transforming the way researchers work with transition metal dichalcogenide quantum dots.
Achieving magnetic order in low-dimensional systems consisting of only one or two dimensions has been a research goal for some time. In a new study published in the journal Nature Communications, Uppsala researchers show that magnetic order can be created in a two-dimensional chessboard lattice consisting of organometallic molecules that are only one atomic layer thick.
A small, thin square of an organic plastic that can detect disease markers in breath or toxins in a building's air could soon be the basis of portable, disposable sensor devices. In a new study in the journal Advanced Functional Materials, professor Ying Diao's research group demonstrated a device that monitors ammonia in breath, a sign of kidney failure.
Hydrogen is an alternative source of energy that can be produced from renewable sources of sunlight and water. A group of Japanese researchers has developed a photocatalyst that increases hydrogen production tenfold.
EPFL researchers have developed a quantum capacitor based on graphene, which has multiple applications. The device is potentially useful in producing a new type of qubit, which is one of the building blocks of quantum computers. It could also be used for highly non-linear circuits.
A research team in China have developed a new CESL method that introduces tensile stress into both the channel and the drift region, improving overall performance by offering low drift resistance, high cut-off frequency and desirable breakdown characteristics. Their work is described in an article appearing this week in the journal AIP Advances, from AIP Publishing.
Most transistors are silicon-based and silicon technology has driven the computer revolution. In some applications, however, silicon has significant limitations. Silicon devices are prone to faltering and failing in difficult environments. Addressing these challenges, Jiangwei Liu, from Japan's National Institute for Materials Sciences, and his colleagues describe new work developing diamond-based transistors this week in the journal Applied Physics Letters, from AIP Publishing.
By precisely measuring the entropy of a supercooled cerium copper gold alloy with baffling electronic properties, physicists in Germany and the United States have provided further evidence about the common causes of high-temperature superconductivity and similar phenomena.
As computer chips become smaller, faster and more powerful, their insulating layers must also be much more robust -- currently a limiting factor for semiconductor technology. A collaborative University of Kentucky-Texas A&M University research team says this new phase of hafnia is an order of magnitude better at withstanding applied fields.
