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.

| 总结: | 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. |
