Quantum noise spectrum in fiber-based nondegenerate phase-sensitive amplification considering phase mismatch and Raman scattering

Wavelength dependence of quantum noise in nondegenerate phase-sensitive amplification in an optical fiber, where signal and its phase-conjugated idler lights are incident into a fiber together with pump light, is theoretically investigated. An analytical formula of the quantum-limited noise figure, that takes Raman scattering into account as well as parametric amplification, is derived based on full quantum mechanical treatment. Using the obtained formula, a calculation example of the noise figure spectrum is also presented, where the pump light phase is adjusted so that the signal gain is maximum at a phase-matched wavelength, supposing multichannel amplification.

考虑相位失配和拉曼散射的基于光纤的非简并相敏放大中的量子噪声谱

从理论上研究了光纤在非简并相敏放大中量子噪声对波长的依赖性,在该放大中,信号及其相位共轭的惰光与泵浦光一起入射到光纤中。基于完全量子力学处理,推导了量子限制噪声系数的解析公式,该公式考虑了拉曼散射以及参数放大。使用获得的公式,还给出了噪声系数谱的计算示例,其中假设了多通道放大,调整了泵浦光的相位,以使信号增益在相位匹配的波长处最大。
