Tiny Flag Salutes Nanotechnology ITHACA, N.Y., March 30 -- In a salute to nanotechnology, Cornell University researchers have etched the world's smallest, full-color American flag on a silicon chip. The flag is part of an elaborate nanofabrication that includes six full-color flags and 15 White Houses, all etched on the chip. NANOWEIGHT: The chip is mouted in this lucite paperweight for presentation to the White House. The size of a postage stamp, the chip has been placed in a Lucite paperweight that will be presented to the White House today in Washington, D.C., by Joshua Wolfe, a...Read full articleRelated content from Photonics MediaArticlesUV-LED Photolithography Imparts Micro FeaturesTechnologies like integrated signal distributing, processing, and sensing networks require basic optical elements such as waveguides, splitters, gratings, and optical switches to be miniaturized....Photonics Spectra April 2024 IssueTeam Develops Laser Printer for PICsThe development of photonic integrated circuits (PICs) is an expensive and time-consuming process.
