据我们所知，我们首次证明了微结构光纤在800 nm处产生的超宽带光通过光谱滤波产生光子数压缩。最大压缩比为4.6分贝，校正后的压缩比为10.3分贝。通过求解包含拉曼散射的非线性量子薛定谔方程，数值分析了超短激光脉冲在光纤中传输的量子动力学，特别是研究了宽带脉冲中各频率模间光子数涨落的量子关联。
To the best of our knowledge, we demonstrate for the first time the generation of photon number squeezing by spectral filtering for ultrabroadband light generated by microstructure fibers at 800 nm. A maximum squeezing of 4.6 dB is observed, corresponding to 10.3 dB after correcting for detection losses. We numerically analyzed the quantum dynamics of ultrashort laser pulse propagation through optical fibers by solving a nonlinear quantum Schrödinger equation that included Raman scattering, especially for the quantum correlation of photon number fluctuation among frequency modes in broadband pulses.
