Abstract
An analysis is made of the properties of a novel type of optical pulse that may propagate stably at normal dispersion in optical fibers. The stability is achieved by permitting two oppositely phased solitons copropagate with the pulse. Because the pulse may be described by the ordinary Schrödinger equation, well-known results can be used for obtaining detailed information about, for example, the pulse shape. In particular, the possibility of observing stable excited pulse states is demonstrated.
