Abstract

Photonic bandgap (PBG) guidance is observed in a solid core photonic crystal fiber (PCF) consisting of silver metaphosphate (AgPO(3)) glass embedded into a silica cladding, realized by vacuum-assisted infiltration of the molten glass into the hollow channels of a commercial silica PCF. Morphologic analysis of the cladding microstructure by optical and scanning electron microscopy reveals the formation of highly homogeneous glass strands along the PCF length. The characteristic transmission spectrum of the fiber shows PBG guidance in the range between 350 and 1650 nm. The exposure of the cladding glass matrix, using 355 nm, 150 ps laser irradiation, allows photo-induced enhancement of the transmission-to-stop-band extinction ratio by ∼60 dB/cm and bandwidth tuning. Numerical calculations of the transmission pattern of the fabricated AgPO(3)/silica bandgap fiber are in good agreement with experiments.

摘要

在由嵌入二氧化硅包层中的银磷酸盐（AgPO(3)）玻璃组成的固体芯光子晶体光纤（PCF）中观察到光子带隙（PBG）引导，这是通过将熔融玻璃真空辅助渗透到商业二氧化硅 PCF 的中空通道中实现的。通过光学和扫描电子显微镜对包层微观结构的形态分析表明，在 PCF 长度上形成了高度均匀的玻璃股。光纤的特征传输谱在 350nm 至 1650nm 范围内显示出 PBG 引导。使用 355nm、150ps 激光辐照暴露包层玻璃基质，允许光致传输到停止带消光比增强约 60dB/cm 和带宽调谐。对所制备的 AgPO(3)/二氧化硅带隙光纤的传输模式进行数值计算与实验结果吻合较好。
