Soliton Dynamics Could Lead to New On-Chip Signal Processing Apps

Researchers have found a way to manipulate a soliton on a silicon chip at both the source and reception end of an optical fiber without altering the wave shape. They used a Bragg gated structure on a silicon substrate. The discovery, which is the result of a collaboration between researchers at the University of Sydney Nano Institute and Singapore University of Technology and Design, could potentially allow for faster photonic communications devices and infrastructure.
