摘要:

在这份报告中,非故意偏离理想的反木堆光子晶体的带隙的影响进行了讨论。这些偏差发生在晶体的纳米加工期间。通过计算分析,它表明,这种类型的晶体的带隙是强大的大多数类型的偏差,涉及到的半径,位置和角度排列的孔。然而,光子带隙对孔的锥形化非常敏感,即,锥形孔代替圆柱形孔。为了获得大体积的三维倒木堆光子晶体,我们的工作表明,与现代制造性能,锥形贡献最显着的倒木堆光子晶体的光子强度的降低。

英文摘要:

In this report the effects of unintended deviations from ideal inverse woodpile photonic crystals on the band gap are discussed. These deviations occur during the nanofabrication of the crystal. By computational analyses it is shown that the band gap of this type of crystal is robust to most types of deviations that relate to the radii, position and angular alignment of the pores. However, the photonic band gap is very sensitive to tapering of the pores, i.e., conically shaped pores instead of cylindrical pores. To obtain three-dimensional inverse woodpile photonic crystals with a large volume, our work shows that with modern fabrication performances, tapering contributes most significantly to a reduction in the photonic strength of inverse woodpile photonic crystals.
