Quantum properties of optical fiber solitons

Gerd Leuchs, Universität Erlangen-Nürnberg

Solitons appear as dynamically stable wave patterns in several areas of physics. One attractive feature is that a soliton is uniquely described by a single mode function, i.e. a pulse envelope, a center wave length, an amplitude and a phase. Studies of the quantum properties have revealed however, that a soliton has an internal multimode structure.
