| 摘 要： | 布拉格光纤是一种一维光子晶体带隙导引光纤.针对布拉格光纤在气体痕量检测领域的应用,设计了传输波段中心波长位于中红外波段的半导体玻璃/有机聚合物基空心布拉格光纤.通过预制棒熔拉法,制备出了中红外空心布拉格光纤的样品.传输谱和弯曲特性测试表明布拉格光纤样品具有两个明显的传输波段,体现了带隙导光的特征.低阶传输波段的中心波长为4.4μm.

| Abstract: | Bragg fiber is one kind of microstructure fiber with one-dimensional photonic crystal layer in its fiber cladding. In this paper, the hollow-core Bragg fiber for trace gas detection, with a transmission band in the mid-infrared band, is designed and fabricated based on semiconductor glass and polymer materials. The measurements of the fiber sample demonstrate its bandgap-guided properties, showing two obvious bandgap guided transmission bands. The central wavelength of the lowest transmission band is 4.4 μm. |
