本文利用反向偏置p-i-n结的硅绝缘体纳米脊波导实现了基于四波混频的相敏放大，实现了一个在线四能级相位再生器。首次采用硅波导作为相敏放大器，实现了14吉比特正交相移键控信号的相位再生。再生器被放置在一个1040公里的色散管理的链路，它示出的相位噪声积累在传输链路中可以减少使用的在线硅基相位再生。
In this paper a silicon-on-insulator nanorib waveguide with reverse-biased p-i-n-junction is used to experimentally demonstrate phase-sensitive amplification based on four-wave mixing for the realization of an in-line four-level phase-regenerator. Phase regeneration of a 14-GBd quadrature phase-shift keying signal is demonstrated for the first time employing a silicon waveguide as phase sensitive amplifier. The regenerator is placed in a 1040-km dispersion-managed link and it is shown that phase noise accumulation in the transmission link can be reduced by the use of the in-line silicon-based phase-regeneration.
