Time Lens Compresses Light To Make Ultrafast Signals


This silicon chip is called a time lens.

Researchers at Cornell University have developed a simple silicon device for speeding up optical data. The device incorporates a silicon chip called a “time lens,” lengths of optical fiber, and a laser. It splits up a data stream encoded at 10 gigabits per second, puts it back together, and outputs the same data at 270 gigabits per second. Speeding up optical data transmission usually requires a lot of energy and bulky, expensive optics. The new system is energy efficient and is integrated on a compact silicon chip. It could be used to move vast quantities of data at fast speeds over the Internet or on optical chips inside computers.

A New Way To Detect Cancer Early

A New Way To Detect Cancer Early 


A prototype device employs the same magnetic phenomenon used to write data to computer hard drives.

A new system for detecting cancer proteins uses the same magnetic phenomenon that lets computer hard drives read and write data. The Stanford University researchers developing the system hope that it will detect cancer in its earlier stages, when it’s easier to treat. MagArray, a startup in Sunnyvale, CA, will commercialize the technology.
