A research team led by Fetah Benabid, University of Bath, has observed for the first time the simultaneous emission of two resonant dispersive waves by optical solitons (waves that maintain their shape while traveling at constant speeds). By designing a special fiber with an extremely small waveguiding feature located in the photonic crystal fiber cladding, the researchers were able to bring the theoretical prediction into the experimental demonstration, creating waves on both sides of the pump. This research appears in the current issue of the Optical Society's Optics Letters. http://www.physorg.com/news146422304.html Physics Thu, 20 Nov 2008 16:51:44 EST news146422304
