【摘要】 通过仿真模拟设计了一种低损耗紫外空芯反谐振光纤。首先，基于有限元法，建立了紫外空芯反谐振光纤的理论模型。其次，通过调整光纤反射层和空气填充比例等参数，并采用反谐振效应控制光的传播和反射，进一步优化了光纤的性能和损耗值。最后，采用有限元法对设计的紫外空芯反谐振光纤进行仿真计算，可得光纤在传输波长为375 nm时取得最小传输损耗，为0.003 26 dB/m，对应的在弯曲半径为5 cm时的弯曲损耗为0.006 25 dB/m，并具有高效率和稳定的模式输出。该研究为开展紫外空芯反谐振光纤的高性能仿真设计提供了重要的参考和指导，并为实际应用提供了更多可能性。更多还原

【Abstract】 A low-loss UV hollow-core anti-resonant optical fiber is designed by simulation. Firstly, a theoretical model of the UV hollow-core anti-resonant optical fiber is established based on the finite element method. Secondly, the performance and loss values of the optical fiber are further optimized by adjusting the parameters of the reflective layer and air filling ratio, and controlling the light propagation and reflection using the anti-resonance effect. Finally, the finite element method is used to simulate the designed UV hollow-core anti-resonant optical fiber,which results in a minimum transmission loss of 0.003 26 dB/m at a transmission wavelength of 375 nm, corresponding to a bending loss of 0.006 25 dB/m at a bending radius of 5 cm, and a high efficiency and stable mode output.An important reference and guidance are provided for the development of high-performance simulation design of UV hollow-core anti-esonant fibers, which offers further possibilities for practical applications.更多还原
