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 ultra-low noise performance and significant G/CE improvement for signal 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 was limited by the practical constraints of phase fluctuations and the need for precise dispersion manipulation in the parametric mixer to achieve noiseless performance over a scalable high count copy number.
