    • A transparent vessel is filled with a mixture solution containing a first photo-curable resin of a low refractive index and a second photo-curable resin of a high refractive index different in curing mechanism. When light at a wavelength capable of curing the first photo-curable resin but incapable of curing the second photo-curable resin is applied to the mixture solution through an optical fiber, the first photo-curable resin can be cured in a state in which the second photo-curable resin is enclosed in the cured first photo-curable resin. Because the refractive index increases according to curing, a self-condensing phenomenon can be generated so that an optical path portion is formed. The optical path portion emits leakage light to its surroundings to thereby form an outer circumferential portion. Then, all uncured resins in the mixture solution are cured. The outer circumferential portion containing a high percentage of the cured first photo-curable resin serves as a clad because the refractive index of the outer circumferential portion is lower than that of the optical path portion.
    • 将透明容器填充有含有低折射率的第一光固化树脂和固化机理不同的高折射率的第二光固化树脂的混合溶液。 当通过光纤将能够固化第一光固化树脂但不能固化第二光固化树脂的波长的光施加到混合溶液时,第一光固化树脂可以在其中 将第二光固化树脂包封在固化的第一光固化树脂中。 由于折射率随着固化而增加,因此可以产生自聚光现象,从而形成光路部分。 光路部分向其周围发射泄漏光,从而形成外圆周部分。 然后,将混合溶液中的所有未固化树脂固化。 由于外周部的折射率低于光路部的折射率,所以含有高比例固化的第一光固化树脂的外周部分用作包层。

    • Transparent parallel planar plates which are members for retaining an optical waveguide are provided erectly in an optical path of light in a transparent vessel in advance. An optical fiber is fixed into the transparent vessel while the optical fiber penetrates the transparent vessel, and an optical sensor is also disposed adjustably. Next, a first photo-curable resin solution is injected into the transparent vessel, and light with a predetermined wavelength for curing is emitted from the optical fiber so that the optical waveguide is self-formed by polymerization reaction. Because the parallel planar plates are transparent, the optical waveguide is formed so as to be extended again from the emission ports of the parallel planar plates. Finally, the optical waveguide is formed so as to reach a bottom surface of the transparent vessel. The optical waveguide has a structure in which the optical waveguide is firmly supported at four points in a forward end surface of the optical fiber, the parallel planar plates and the bottom surface of the transparent vessel. Accordingly, a firm optical waveguide device is formed.
    • 用于保持光波导的构件的透明平行平板预先在透明容器的光路中直立设置。 光纤固定在透明容器中,同时光纤穿透透明容器,光学传感器也可调整地设置。 接着,将第一光固化树脂溶液注入到透明容器中,从光纤射出固化用的规定波长的光,使得光波导通过聚合反应自成型。 由于平行平板是透明的,所以光波导形成为从平行平板的发射端口再次延伸。 最后,形成光波导以到达透明容器的底面。 光波导具有这样的结构,其中光波导被牢固地支撑在光纤的前端表面,平行平板和透明容器的底表面的四个点处。 因此,形成牢固的光波导装置。
