摘要：
A multiple access interference elimination scheme based on nonlinear polarization rotation (NPR) is proposed for ultrashort pulse optical code-division multiple access (OCDMA). This scheme is experimentally investigated in a four-user and 2.5-Gb/s coherent OCDMA system encoded/decoded by 127-chip superstructured fiber Bragg gratings. The measured bit-error-rate results of the NPR-based thresholder are also compared with those of a conventional supercontinuum-based thresholder in both the back-to-back and 20-km transmission cases. Our proposed scheme has the advantage of colorless operation over C-band.
