Betty Lise Anderson wasn't looking for the Holy Grail of optical interconnections, but she thinks she may have helped find it. The associate professor of electrical engineering at Ohio State University (OSU) worked with Professor Emeritus Stuart A. Collins Jr. in the ElectroScience Laboratory developing an optical true-time delay for phased-array radar. And then one day, the idea for the optical interconnect hit them. "We reasoned that with a few modifications the device could help eliminate data-transfer bottlenecks," says Anderson. She says the new device transfers data faster than other devices, in electronic hubs that transfer light pulses to electrical signals and then back into light pulses, when downloading information over the Internet. The interconnect uses mirrors for reflecting the light, instead of transferring the light into electrons and then back into light again. "We joked that if we could find a way to make this work, we could rule the universe," says Anderson. The new patented device is a silicon computer chip covered with hundreds of thousands of tiny mirrors. Each mirror measures only a few tens of millionths of a meter across. The mirrors catch individual beams of light from fiber optic cable and reflect them to their destination, bypassing the traditional electronics that slow optic transmission. Andersen explains that the OSU design is tolerant of vibrations and has a built-in redundancy. "If one micromirror fails, another will take its place," she says. The OptiConnect Company is developing and will eventually commercialize the technology. For more information, call (614) 675-4100 or go to www.osu.edu.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
