A team of scientists from Rutgers University and National Institute of Standards and Technology believe that a technology could result in optical switches with sub-square-micron footprints, potentially allowing densely packed switching fabrics on chips. The scientist have shown that an optical signal can be modulated in a 200 nanometer-high waveguide. They propose that when one of these modulators is a placed next to a similar static device, it could act as a 2x2 switch. Optical switches could be scaled closer to electronic device dimensions.
