我们提出了一种新技术来对光子晶体光纤（PCF）中的气孔进行精确选择性渗透。为了进行渗透过程，PCF的端面被掩模覆盖，该掩模是通过从横向的飞秒激光刻印制造的。该方法克服了最大掩模厚度的传统限制。进一步提出了分析模型，并证明了掩模中制造的通道直径的准确确定。
We propose a new technique to perform precise selective infiltration of an air hole in the photonic crystal fiber (PCF). To carry out the infiltration process, the end face of the PCF is covered by a mask, which is fabricated by femtosecond laser inscription from the lateral direction. This proposed method overcomes the conventional limitation of maximum mask thickness. An analytical model is further proposed and demonstrated accurate determinations of the fabricated channel diameter in the mask.
