An adaptive delay control to maintain time-interleaving condition of multi-channel input signals of all-optical amplitude limiter based on saturation of four-wave mixing (FWM) in a nonlinear fiber is demonstrated. The delay control utilizes as a monitor signal the optical power after the nonlinear fiber at a wavelength that is affected by interchannel FWM in the fiber. When the scheme is applied to 2 x 10 Gbit/s return-to-zero differential phase-shift keying signals where the time separation between the input channels is intentionally changed randomly, the delay control works well and error free detection after transmission is obtained.
