The polarization dependent optical confinement factor of waveguide structure with mixed strained layer multi quantum well has been discussed in this paper.
本文从理论上对混合应变量子阱结构(既有张应变量子阱又有压应变量子阱)的光学限制因子进行了讨论。
The PCF can be used to improve the pump efficiency of EDFAs because its power confinement factor is higher than that of the conventional erbium doped fibers.
结果表明，光子晶体光纤单模工作波长范围比较宽，功率限制因子比较高，可用于制作更高抽运效率的光纤放大器。
Meanwhile extinction ratio of converted signal can be improved with low probe power, short probe wavelength, long cavity length, high confinement factor, and large biased current.
减小探测光输入功率，选取短波长探测光波长，增加半导体光放大器的腔长和模场限制因子以及大的偏置电流可提高转换光消光比；
Although small QW has smaller optical confinement factor and smaller ratio of carriers injected into QW, it can provide higher mode gain because of its smaller mixing between valence bands.
小阱宽的量子阱虽然光学限制因子和载流子注入比例都较小，但由于其价带耦合小于宽量子阱，从而具有高的模式增益，说明量子阱的能带结构对其光学特性有决定性的作用。
