Largest-scale silicon photonic switch: Low loss optical design enables up to 2,500 switch elements on 1 x 1 cm chip
Today's explosion of video and Internet data is driving unprecedented traffic demand within datacenters. With data transfer rates exceeding 100 gigabits-per-second (Gb/s), communication between servers requires optical switches ...
Popular origami pattern makes the mechanical switch
An origami paper-folding pattern called the square twist is the basis of a microscopic switch that Cornell physicists say could lead to origami-inspired materials and machines.
Simulations provide new insight into emerging nanoelectronic device
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential ...
Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Bacteria 'hotwire their genes' to fix a faulty motor
Researchers at the University of York are part of a team of scientist that has discovered how bacteria can restart their 'outboard motor' by hotwiring their own genes.
Nano switch could store memory using coordinated 'dance' of atoms

A research team led by Prof. Hiroshi M. Yamamoto of the Institute for Molecular Science, National Institutes of Natural Sciences has developed a novel superconducting transistor which can be switched reversibly ...
Smartphone kill switches credited with stifling theft
Kill switches that render stolen smartphones useless were credited on Wednesday with stifling robberies and thefts in London, New York City, and San Francisco.
Genetic safety switches could help curb potential bioterror risks
The potential threat of bioterrorism using man-made biological organisms could be reduced, thanks to a new method developed by scientists.
Black hole on a diet creates a 'changing look' quasar
Yale University astronomers have identified the first "changing look" quasar, a gleaming object in deep space that appears to have its own dimmer switch.
Modern genetics confirm ancient relationship between fins and hands
Paleontologists have documented the evolutionary adaptations necessary for ancient lobe-finned fish to transform pectoral fins used underwater into strong, bony structures, such as those of Tiktaalik roseae. ...
Researchers create 'green' process to reduce molecular switching waste
Dartmouth researchers have found a solution using visible light to reduce waste produced in chemically activated molecular switches, opening the way for industrial applications of nanotechnology ranging from ...
New research could transform high speed optical networks
There is an ever growing demand for high speed internet communication systems. New research has shown optical switching technology built on nanoantenna reflectarrays and tunable materials could transform ...
Electronic switches on the molecular scale
A molecular electronic switch is a junction created from individual molecules that can alternate between two or more stable states, making the switch act as a conductor or an insulator. These switches show ...
