Andrew Weiner and Daniel Leaird found a way to put a single pulse of light into an arrayed wave guide grating and get a rapid-fire burst of 21 light pulses out of it, with each pulse separated by only two-trillionths of a second. It works similarly to a prism, separating white light by wavelength. The unique properties of the device allow generation of identical, wavelength-shifted pulse trains for communication and photonic signal processing. The discovery could help satisfy demand for increasing network bandwidths. The pair of Purdue University engineers say their device has transmission speeds that are ten times faster than anything currently available. "ISPs are primarily operating at 10 Gbytes/sec per channel, times very many wavelength channels," says Weiner. "Our work can impact higher speed systems, 100 Gbytes/sec per channel and above," he says. Wiener and Laird's idea is to build a module that takes parallel electric data input and converts it into a fast serial optical data stream suitable for fiber transmission.

Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
