The birth of the theory of relativity and the quantum theory early this century , the breakthrough in the semi - conductor technology in the 1950s and the discovery of the double spiral structure of dna have set off a round of geometrical development of science and technology in the world 本世纪前期相对论和量子论的诞生， 50年代半导体技术的突破和脱氧核糖核酸双螺旋结构的发现，引发了世界科学技术的迅猛发展。
Then the propagation of different kind of fibers is analyzed according to the ray optics . the novel idea that the quantum theory is introduced in the ray optics has been brought forward , and the theory system of quantized ray optics has been primarily constructed in the paper . according to the quantized ray optics , the modes of wave - guide and optical fiber , soliton theory and the fiber coupling are initially studied 先对传统的波动光学理论做了概括，主要利用光线光学的理论对光在折射率分布不同光纤中的传输做出了分析，并从光线光学出发引入量子力学的观点，建立了光线量子论的理论体系，应用该理论对光波导、光纤中的光模式、光孤子理论、光纤耦合几个光纤应用领域做了初步探讨，提出了新的展望。
