| Abstract: | Coupling equation of counter cross-phase modulation (XPM) is proposed.In nonlinear optical loop mirror (NOLM),nonlinear phase shift difference between the co-propagating and the counter-propagating signal in transmission process is gotten.The switching characteristics on Gaussian pulse,the effect of XPM on de-multiplexer which adopts NOLM and the progression without amplifier in an experiment adopting NOLM in all optical routing are analyzed.In the end,we discuss the switching characteristics on non-return zero (NRZ) codes. |
