SEATTLE, July 3, 2012 — Work over the past decade to harness the energy-generating mechanism of the sun has now yielded bright high-energy light needed to etch smaller microchips. The microchip industry now uses 193-nm UV light, which cannot etch circuits any smaller than those currently being made. The future...Read full articleRelated content from Photonics MediaARTICLESAgarwal Group Puts Spin on PhotonsThe University of Pennsylvania’s (Penn) Agarwal Group, headed by professor Ritesh Agarwal, seeks to understand how light interacts with small-scale nanostructures.
