Wavelength division multiplexing-based networks suffer from blocking probability due to wavelength contention resolution. Such a problem can even be worth when the advanced coherently modulation formats such as M-array quadrature amplitude modulation is used to increase the channel capacity beyond 100 Gbit/s. This paper presents theoretical study of cascaded sum frequency generation and difference frequency generation based tunable wavelength conversion in a periodically poled lithium niobate waveguide as a trivial solution to the wavelength blocking problem when advanced signal modulation formats are considered. It is shown numerically that wavelength conversion of single channel up to 1 Tbit/s would be possible with a 3 cm long wavelength converter.

分析基于 PPLN 的 cSFG/DFG 波长转换,容量超过 100 Gb/s

由于波长争用解决方案,基于波分复用的网络受到阻塞概率的影响。当使用先进的相干调制格式(例如 M 阵列正交幅度调制)将信道容量增加到 100 Gbit/s 以上时,这样的问题甚至是值得的。本文介绍了在周期性极化铌酸锂波导中基于级联和频生成和差频生成的可调波长转换的理论研究,作为考虑高级信号调制格式时波长阻塞问题的简单解决方案。数字表明,使用 3 cm 长波长转换器可以实现高达 1 Tbit/s 的单通道波长转换。
