We numerically study cross-phase modulation (XPM) statistics in 100% precompensated wavelength-division-multiplexing transmission with on-off keying (OOK) and differential phase-shift keying (DPSK) formats. XPM and its randomness are determined by nonlinear diffusion bandwidth and specific modulation format in the target channel. XPM degradation in DPSK channels shows much less stochastic than that...
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against...
