Here we report on the direct laser writing fabrication of Fabry-Perot-type planar microcavities in a three-dimensional (3D) photonic crystal (PhC) embedded within a high-refractive nonlinear chalcogenide glass (ChG) film. The fabricated planar microcavities in a nonlinear ChG 3D PhC facilitate the observation of resonant modes inside the stop gap. The experimental results show that the length of the planar cavity can be well controlled by the fabrication power and thus be used to tune the defect modes. The tunability of the observed defect modes is confirmed by the theoretical prediction.
我们在此报告了在嵌入高折射率非线性硫属玻璃 (ChG) 薄膜中的三维 (3D) 光子晶体 (PhC) 中直接激光写入法制作法布里-珀罗 (Fabry-Perot) 型平面微腔的情况。在非线性 ChG 3D PhC 中制作的平面微腔可便于在停止带内观察共振模式。实验结果表明，平面腔的长度可以通过制作功率很好地控制，从而可以用于调谐缺陷模式。观察到的缺陷模式的可调谐性已通过理论预测得到证实。
