Demonstration of data remodulation for upstream traffic in WDM access networks using injection-locked FP laser as modulator

摘要

We propose and demonstrate an upstream-traffic remodulation scheme based on injection locking of a FP laser diode on the downstream wavelength. The original 10 Gbit/s downstream data are largely suppressed, allowing simultaneous direct modulation of 1-Gb/s upstream data with improved signal quality.
