We numerically investigated the interaction between the intense solitonic pulse and the weak signal pulse which copropagate with anomalous dispersion in different photonic bandgaps of the anti-resonant photonic bandgap fibers. When soliton pulse and signal pulse and has the same group velocities, two color soliton are formed. Whereas when their group velocities are not the same but close, signal pulse oscillates around the center of soliton pulse in time domain and the center wavelength of signal pulse also oscillate around the wavelength which matches its group velocity with soliton pulse. The dynamics of the oscillatory motion is investigated based on a vibration equation. The wavelength dependence of output pulse in the pulse trapping process is demonstrated and this phenomenon may be used to make tunable wavelength converter.
