We experimentally demonstrate, for the first time to our knowledge, a phase-sensitive amplifier based on frequency nondegenerate parametric amplification in optical fiber, where the input signal-idler pair is prepared all-optically. Using two fiber-optic parametric amplifier sections separated by a fiber-based wavelength-dependent phase shifter, we observe and investigate phase-sensitive gain profile in the 1550 nm region both experimentally and theoretically. The realized scheme automatically generates gain-defining phase that is environmentally stable, making it advantageous for building phase-sensitive transmission links.
据我们所知，我们首次通过实验证明了一种基于光纤中频率非简并参量放大的相敏放大器，其中输入信号-闲频对是全光制备的。利用由基于光纤的波长相关移相器隔开的两个光纤参量放大器部分，我们在1550nm区域通过实验和理论观察并研究了相敏增益分布。所实现的方案自动生成环境稳定的增益定义相位，这使其有利于构建相敏传输链路。
