【摘要】 本文从D.Gloge提出的最佳模色散的波导结构出发,设计了制备梯度型P₂O₅-SiO₂系光纤折射率剖面参数α≈2的沉积程序。根据实验结果修正了假定的设计程序,并获得了α=1.95±0.1的折射率剖面。讨论了影响折射率剖面的各种因素。更多还原

【Abstract】 A deposition technique program was initially designed to fabricate graded optical fibresin the system P₂O₅-SiO₂ with refractive index profile of α≈2, based on the waveguidestructure of minimum dispersion as suggested by D. Gloge. Experiments resulted in the mo-dification of the program,and a refractive index profile of α=1.95±0.1 was obtained.Va-rious technological parameters effecting the refractive index have been discussed.更多还原
