Based on the bimorph piezoelectric vibrator,a piezoelectric pump with two active valves was designed and manufactured.

以双晶片压电振子为驱动元件,研制了两主动阀式压电泵。

The influences of the thickness of defect layer on the resonant wavelength and its quality factor in one-dimensional photonic crystal cavity were studied with optical transmission matrix.

利用光学传输矩阵法研究了一维光子晶体谐振腔的谐振波长、品质因子和缺陷层厚度之间的变化关系,发现谐振腔内存在不同级次的谐振模式;对于同一级次的谐振模式,品质因子在某一波长(λm)时达到极大值,该波长恰为光子晶体反射率最高处所对应的波长,也是该光子晶体的布拉格共振反射波长;在λm处,品质因子随级次的增加而线性增加;品质因子随周期层数增加而指数增加,但其增长因子与模式级次无关,也与周期数无关,只与谐振波长有关;对于所有级次的谐振模式,增长因子在λm处达到最大值。
