利用时域有限差分方法,理论研究了由介电常数为8.9的介质柱排列在空气背景中组成的二维正方晶格光子晶体耦合腔光波导的传输特性.理论模拟结果表明,将微腔紧邻的两个圆形介质柱改变为椭圆形.通过改变椭圆的旋转角度能够调控导模的频率范围.通过将相邻微腔两边的椭圆形设置为不同旋转角度,可以在保证高传输效率的同时进一步地降低导模的群... 相似文献

1. IntroductionRecently, the surface property requirement ofPolyethylene Terephthalate (PET) has becomehigher and higher with its ever-increasing applications. To improve its surface properties, variousmethods such as plasma treatment have been introduced. In the plasma, there are sufficient amountof energetic particles as well as the same amount ofnegative and positive charged particles. By bombingsuch as etching the surf are of solid-state material andtransferring energy, the physical and … 相似文献
