| Abstract: | The coupling of two nonequal-amplitude linear polarization solitons in lowellipticity birefringent optical fibers is analytically investigated. By analogy withparametrically excited solitary waves in a trough resonator, the mechanism of energytransform between coupled solitons in two channels is discussed in a dynamic POint of view.The first-switching distance L1 and the alternative period L2 are numerically determined andthe cause of L1 > L2 is analyzed. According to the coupling behavior of solitons, an idea ofall-optical soliton switching is proposed, which permits to fluCtuation of the amplitudes andother parameters of the control and signal Pulses in larser ranges. |
