New Breed of Optical Soliton Wave Discovered

Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics, and colleagues have discovered a new type of optical soliton wave that travels in the wake of other soliton waves, hitching a ride on and feeding off of the energy of the other wave. Solitons are localized waves that act like particles. Professor Vahala likens these newly discovered solitons to pilot fish, carnivorous tropical fish that swim next to a shark so they can pick up scraps from the shark's meals. And by swimming in the shark's wake, the pilot fish reduce the drag of water on their own body, so they can travel with less effort. [Caltech story]
