多段光纤链路中的FWM效率 [PDF]

Guangtongxin yanjiu, 2008
通过推导由多段光纤构成的光纤链路中的四波混频（FWM）效率,找出了影响全光波长变换的FWM效率的因素,进而利用MATLAB软件成功模拟出任意多段光纤链路中的FWM效率。以由7段光纤组成的光纤链路为例,通过调节影响混频效率的各种参数的值,得到了获取最佳混频效率的参数取值范围,并可进一步获得稳定的波长变换效率。

Coherent Control of Perfect Optical Vortex Through Four-Wave Mixing in an Asymmetric Semiconductor Double Quantum Well

Frontiers in Physics, 2022
A scheme for the coherent control of perfect optical vortex (POV) in an asymmetric semiconductor double quantum well (SDQW) nanostructure is proposed by exploiting the tunneling-induced highly efficient four-wave mixing (FWM).

Pump-probe detuning dependence of four-wave mixing pulse in an SOA [PDF]

, 2007
Four-wave mixing (FWM) between 2-ps pulses in a multiquantum-well semiconductor optical amplifier (SOA) is presented. The conjugate pulses are fully characterized using the frequency-resolved optical gating technique.
