Abstract

Under investigation in this paper is a complex modified Korteweg-de Vries(KdV)equation,which describes the prop-agation of short pulses in optical fibers.Bilinear forms and multi-soliton solutions are obtained through the Hirota method and symbolic computation.Breather-like and bound-state solitons are constructed in which the signs of the imaginary parts of the complex wave numbers and the initial separations of the two parallel solitons are important factors for the interaction patterns.The periodic structures and position-induced phase shift of some solutions are introduced.

Key words
