Multi-stage Carrier Phase Recovery and Nonlinear Polarization Crosstalk Canceller for XPM Mitigation
Coherent communications Nonlinear optics fibers
2015/5/26
Novel XPM mitigation technique by coordination of carrier phase recovery and nonlinear polarization crosstalk canceller is proposed. It doubles the Q improvement over conventional method in 112Gb/s DP...
Reduction of Crosstalk by Trench-Assisted Multi-Core Fiber
Fiber characterization Fiber design fabrication
2015/5/26
Trench-assisted multi-core fiber (TA-MCF) is proposed to achieve high dense MCF design with a solid structure. The crosstalk value at 1.55 μm of fabricated TA-MCF is estimated to be –35 dB at 100 km.
We characterize optical crosstalk and the associated bit-error rate degradation in silicon nanowaveguides. Our results indicate that the crosstalk decreases with increasing modulation frequency and de...
