Optical thresholders based on nonlinear optical loop mirror (NOLM) and nonlinear amplifying loop mirror (NALM) for interference suppression in optical code division multiplexing (OCDM) system are evaluated. The ratios of auto-correlation peak to the maximum wing level (P/W) and cross-correlation level (P/C) were used to quantitatively measure the interference suppression characteristic of the optical thresholders. The theoretical simulations show that system performance could be improve apparently by NOLM or NALM based on high nonlinear fiber (HNLF), and the results are validate by the corresponding experimental investigation in the 40 Gbit/s OCDM system.
