Michael Ward is creating crystals that may eventually improve lasers and optical switching devices. The University of Minnesota researcher and professor of materials science designs solid-state structures. The crystals make possible the changing of red light to green or blue. Ward's crystals could, for example, be an enabler of blue light lasers. He points out that blue lasers, although difficult to build, are desirable for telecommunications applications because information transmits faster at blue light's higher frequencies and shorter wavelengths. "What we are doing is crystal engineering," says Ward. "We are able to design a crystal with a polar structure," he adds. Because they are polar, the crystals double the frequency of light. In optical switching, Ward's crystals function as transmitters for passing information. "There are other materials that can do what our crystals do, but they don't have the thermal robustness that these crystals have," says Ward.

Sensor deployment in automated factories should be done slowly and conservatively, otherwise engineers may face the loss of hundreds of thousands or even millions of dollars, an Internet of Things expert will tell attendees at the upcoming Design & Manufacturing Show in Minneapolis.
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.
