Light can carry data at much higher rates than electricity, but it has always been too expensive and difficult to use light to transmit data among silicon chips in electronic devices. Now, electrical engineers at Stanford have solved a major part of the problem. They have invented a key component that can easily be built into chips to break up a laser beam into billions of bits of data (zeroes and ones) per second. This could help chips output data at a much higher rate than they can now.
’’Most of the high-performance optoelectronics-the stuff that connects optics and electronics-are made from moderately exotic materials, and putting them together with silicon has been hard,’’ says David A. B. Miller, the W. M. Keck Foundation Professor of Electrical Engineering. ’’In the end you’d like to have one platform to make everything, and it would be good if that platform were based on silicon.’’
That single platform is now much closer to reality. The discovery Miller and researchers including James Harris, the James and Ellenor Chesebrough Professor in the School of Engineering, announce in the Oct. 27 issue of the journal Nature is one that may enable a tiny modulator-a solid-state shutter-made of silicon and germanium. Because silicon and germanium are elements common in semiconductor manufacturing, the modulator could be built into chips easily and cheaply.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
