Breck Hitz

As several laboratories around the world pursue silicon lasers, other researchers are exploring a variety of silicon-based optical components. Directional couplers are the basic building blocks for a host of optical devices, from multiplexers to switches. Recently, scientists with NEC Corp. and the Optoelectronic Industry and Technology Development Association, both in Tsukuba, Japan, and with the University of Tokyo performed what they believe is the first investigation of silicon nanowire directional couplers. Figure 1. The tiny, silicon-nanowire directional coupler (top) coupled...Read full article
