研究目的
To compare degenerate one- and three-mode PS parametric multicasting in terms of stability, phase manipulation, gain, and conversion efficiency, as well as noise performance.
研究成果
The study demonstrated that dual-pump degenerate one- and three-mode PS architectures in a dispersion-engineered parametric mixer offer significant improvements in noise performance and BER sensitivity for wavelength multicasting. The three-mode operation showed a record low NF of 1 dB and a 2-dB BER sensitivity improvement over the one-mode case, highlighting the superiority of multi-mode PS architecture.
研究不足
The study focused on the unsaturated regime for ultra-low noise performance, with potential limitations in practical applications requiring high signal input power. The experimental NF results showed discrepancies from the quantum limit, attributed to inadequate noise localization due to SBS limited mixer length.
