摘要： A light-conducting glass structure, the refractive index of which in each cross section perpendicular to the centre line or plane along which light is to advance of the structure decreases progressively from the centre line or plane toward the outer surface of the structure, and the rate of decreasing the refractive index is smaller at the vicinity of at least either end surface being transverse to the centre line or plane than that in the other part of the glass structure. The decrease of refractive index occurs by varying the concentration within the glass structure of at least two kinds of cations (They differ from each other in their contributions to increasing of refractive index.) constituting modifying oxides. The rate of decreasing refractive index at the vicinity of at least either end surface of the glass structure is made to carry out by such a manner that the cation within the glass structure (Which is either of at least two kinds of cations mentioned above and has higher contributions to the increase of refractive index than that of the other.) is substituted by another cation from an external cation source in a greater extent, or a stretching ratio of a part to be an end surface of the glass structure having a certain rate of decreasing refractive index is adjusted to be smaller.
摘要翻译：导光玻璃结构的折射率在垂直于结构的光的中心线或平面的每个横截面中的折射率逐渐从中心线或平面朝向结构的外表面逐渐减小，并且在至少任一端面的附近，折射率的降低率比玻璃结构的其他部分横向于中心线或平面的距离更小。折射率的降低通过改变构成改性氧化物的至少两种阳离子（它们彼此不同于它们对折射率增加的贡献）的玻璃结构内的浓度而发生。使玻璃结构的至少任一端面附近的折射率降低的速率通过使玻璃结构内的阳离子（其为上述至少两种阳离子，并且具有对折射率增加的贡献高于另一个）由外部阳离子源的另一阳离子被更大程度地取代，或者具有一定速率的作为玻璃结构的端面的部分的拉伸比降低折射率被调整为更小。
