Single optical pulse electronics have potential for communications, sensors and navigation

US team devises method for creating ‘solitons’ and hope for applications in optical technologies Solitons are a special kind of wave. First noticed in water in the 19th century, they are a single pulse that moves at a constant velocity without losing its shape. They also occur in light, and researchers at Purdue University in Indiana are investigating their generation and use. Purdue researchers have used tiny microrings (top left) to generate solitons.
