研究了利用微流体渗透技术对缝隙光子晶体波导中慢光工作波长的调谐。利用二维平面波展开方法,我们数值计算表明,工作波长可以从C波段到L波段移动,简单地通过选择渗透流体的折射率。研究还发现,随着渗透流体折射率的变化,在不同的工作波长下,群速度色散有轻微的变化。该设计为在开槽光子晶体波导中实现慢光工作波长的后加工调谐提供了可能性,并允许器件针对不同的应用进行优化。
Tuning of the operating wavelength of slow light in the slotted photonic crystal waveguide using microfluidic infiltration has been investigated. Using 2D plane wave expansion method, we numerically demonstrate that the operating wavelength can be shifted from the C to L band, simply by choosing the refractive index of the infiltrated fluid. It is also found that, as the refractive index of the infiltrated fluid changes, the group velocity dispersion has slight variation at different operating wavelength. This design opens the possibility for post-fabrication scheme of tuning the operating wavelength of slow light in slotted photonic crystal waveguide, and allows the device to be optimized for different applications.
