可加工容差的高品质因数光子晶体微腔

Fabrication-tolerant high quality factor photonic crystal microcavities

Kartik Srinivasan, Paul E. Barclay, Oskar Painter

摘要:

提出了一种二维光子晶体微腔的设计,该微腔支持波长尺度的体积谐振模式,计算得到的品质因数(Q)对腔体几何形状的偏差不敏感,在Q~ 2 × 10^4的水平上。通过对硅中制造的无源腔进行基于光纤的测量,证实了腔设计的鲁棒性。对于工作在λ = 1500 nm波段的微腔,在腔体几何形状的显著变化和谐振模式归一化频率偏移高达标称值的10%的情况下,测量到1.3- 4.0 × 10^4之间的品质因数。

英文摘要:

A two-dimensional photonic crystal microcavity design supporting a wavelength-scale volume resonant mode with a calculated quality factor (Q) insensitive to deviations in the cavity geometry at the level of Q~2x10^4 is presented. The robustness of the cavity design is confirmed by optical fiber-based measurements of passive cavities fabricated in silicon. For microcavities operating in the lambda = 1500 nm wavelength band, quality factors between 1.3-4.0x10^4 are measured for significant variations in cavity geometry and for resonant mode normalized frequencies shifted by as much as 10% of the nominal value.
