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.

Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
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.
