通过利用其可定制的色散特性来实现相位匹配，在超过 1000 nm 的波长范围内演示了光学微光纤 (OMF) 中基于四波混频 (FWM) 的参量放大。仿真表明，对于满足 FWM 能量守恒条件的任何一组波长，都可以在两个直径处发生基模相位匹配。使用高功率脉冲源与周期性极化石英光纤 (PPSF) 结合工作，产生基波和二次谐波信号，进行实验，以研究 OMF 中 FWM 参数放大的可能性。对于接近两相匹配直径的直径，记录了三次谐波波长处闲频输出功率的大幅增加。考虑到 PPSF 的热漂移和系统中的其他损耗后，在 6 毫米长的微光纤中观察到初始信号的总放大超过 25 dB。
Four-wave mixing (FWM) based parametric amplification in optical microfibers (OMFs) is demonstrated over a wavelength range of over 1000 nm by exploiting their tailorable dispersion characteristics to achieve phase matching. Simulations indicate that for any set of wavelengths satisfying the FWM energy conservation condition there are two diameters at which phase matching in the fundamental mode can occur. Experiments with a high-power pulsed source working in conjunction with a periodically poled silica fiber (PPSF), producing both fundamental and second harmonic signals, are undertaken to investigate the possibility of FWM parametric amplification in OMFs. Large increases of idler output power at the third harmonic wavelength were recorded for diameters close to the two phase matching diameters. A total amplification of more than 25 dB from the initial signal was observed in a 6 mm long optical microfiber, after accounting for the thermal drift of the PPSF and other losses in the system.
