利用聚焦离子束刻蚀技术在亚波长石英光纤上加工出周期性的纳米沟槽，实现了布拉格光栅的实验制作。利用这种NFBG结构，我们已经实现了双腔系统。这种谐振腔的典型精细度为F = 20 - 120，谐振透射率为30 - 80%。此外，这种NFBG的结构对称性导致在偏振腔中的偏振选择模式。由于在导模中对场的强限制，这种双折射腔可以成为腔QED的一个很有前途的工作平台。
We present the experimental realization of nanofiber Bragg grating (NFBG) by drilling periodic nano-grooves on a subwavelength-diameter silica fiber using focused ion beam milling technique. Using such NFBG structures we have realized nanofiber cavity systems. The typical finesse of such nanofiber cavity is F ∼ 20 - 120 and the on-resonance transmission is ∼ 30 - 80%. Moreover the structural symmetry of such NFBGs results in polarization-selective modes in the nanofiber cavity. Due to the strong confinement of the field in the guided mode, such a nanofiber cavity can become a promising workbench for cavity QED.
