| 摘 要： | When two optical pulses copropagate inside a single-mode fibre, intensity-dependent refractive index couples the pulses through a cross-phase modulation （XPM）. We show that a second-harmonic generation （SHG） on a continuous-wave background is possible in the optical fibre induced by the XPM effect. By means of a multiscale method the nonlinearly coupled envelope equations for the SHG are derived and their explicit solutions are provided and discussed.
