Transmitting data with a semiconductor laser
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences demonstrated a laser that can emit microwaves wirelessly, modulate them, and receive external radio frequency signals.
“The research opens the door to new types of hybrid electronic-photonic devices and is the first step toward ultra-high-speed Wi-Fi,” said ... » read more
Measuring molecules
The Technical University of Munich (TUM) has developed a new metrology technique that determines the properties of individual molecules.
The technique, called single-molecule excitation–emission spectroscopy, improves upon the traditional methods to explore molecules. The traditional method, dubbed single-molecule spectroscopy (SMS), is not new and is used to analyze f... » read more
China’s powerful laser
The Shanghai Superintense-Ultrafast Lasers Facility (SULF) in China claims to have demonstrated the world’s most powerful laser.
The ultra-intense, ultra-fast laser is said to have delivered a peak power of more than five petawatts. This is supposedly the largest peak-power laser pulse ever measured on record. A petawatt is equivalent to one quadrillion watts.

Microbunching EUV
Researchers at the SLAC National Accelerator Laboratory have provided a status report on its ongoing efforts to develop a steady-state microbunching (SSMB) technology.
SSMB is a technology used within a storage ring, which is a large-scale, circular particle accelerator. An SSMB mechanism produces a high-power radiation source within the ring. This, in turn, could enable a... » read more
Brain-inspired computing
Lawrence Livermore National Laboratory (LLNL) has purchased a brain-inspired supercomputing platform for deep learning developed by IBM Research.
Based on a neurosynaptic computer chip called IBM TrueNorth, the scalable platform will process the equivalent of 16 million neurons and 4 billion synapses. It will consume the energy equivalent of a tablet computer.

Diamond shock waves
For years, the industry has been exploring the use of diamonds for electronics applications. Diamonds could be used to reduce heat in electronic systems. In addition, diamond FETs are also intriguing. Diamond has a wide bandgap (5.45 eV), a high breakdown field (10MV/cm), and high thermal conductivity (22W/cmK).
But it could take years before diamond FETs reach the mains... » read more
Table-top EUV
Swinburne University of Technology has developed a table-top extreme ultraviolet (EUV) laser power source. The source could be used to develop a system for use in metrology and other applications.
The table-top setup is a new way to generate bright beams of coherent EUV radiation. It may offer a cost-effective alternative to large-scale facilities, such as synchrotrons or free... » read more
Transparent armor
The U.S. Naval Research Laboratory (NRL) has developed transparent armor. The technology is actually a hard transparent ceramic, based on a material called spinel. Spinel is a magnesium aluminate compound. Spinel is also a gemstone, which could come in various colors.
NRL has devised a fabrication process to create the technology, which is harder and superior to glass, sap... » read more
Swedish nano
Sweden’s Lund University plans to build a pilot production facility for startups in the field of nanotechnology.
The facility would be used for Swedish companies and researchers to build products. This is for companies who do not have the funds to build their own facilities or buy expensive equipment. The project originates from the successful research into nanowires at Lund ... » read more
Making sounds with atoms
What is the sound of one hand clapping? Perhaps a better question is what is the sound of an atom?
Chalmers University of Technology has demonstrated the ability to make a sound with an atom. More specifically, researchers have made acoustic waves with an artificial atom. In doing so, researchers have demonstrated quantum physics with sound taking on the role of lig... » read more
Experts at the Table: What are the limitations today that are preventing 3D-ICs from becoming mainstream, and which companies pushing to make it happen?
Experts at the Table: The challenges to build a single chip to handle future autonomous functions of a vehicle span many areas across the design process.
