Sun discovers more efficient phased arrays

February 21, 2013

Phased arrays are light sources that don’t move, but can project a beam in any direction. In a recent issue of Nature, researchers from MIT’s Research Laboratory of Electronics (RLE) describe a 4,096-emitter array that fits on a single silicon chip whose wide range of potential applications include more efficient laser rangefinders; medical-imaging devices; and even holographic televisions that emit different information when seen from different viewing angles. Michael Watts, an associate professor of electrical engineering published the paper along with first author Jie Sun, a graduate student in Watts’ lab, and Sun’s fellow graduate students Erman Timurdogan, Ami Yaacobi, and RLE postdoc Ehsan Shah Hosseini.
