摘要： In a retainer holding a plurality of optical transmission members at given positions, a position of an optical center of each of the optical transmission members is measured at a high measuring accuracy. In this case, a lens system forming a beam waist in its output beam is arranged so as to oppose to an end face of each of the optical transmission members, and then the output beam is input to the optical transmission member, and subsequently a position of the lens system is measured when a light intensity of a beam emanated from the optical transmission member is maximum, and thereafter a position of the optical transmission member is calculated from the measured value.

摘要： A V groove and guide grooves are defined in a ceramic substrate, and an optical fiber is fixedly disposed in the V groove by the ceramic substrate and a cover, thereby producing a first optical waveguide chip. A V groove and guide grooves are also defined in another ceramic substrate, and an optical fiber is fixedly disposed in the V groove by the ceramic substrate and a cover, thereby producing a second optical waveguide chip. The first optical waveguide chip has an end face inclined to the direction of propagation of light through the optical fiber thereof, and the second optical waveguide chip also has an end face inclined to the direction of propagation of light through the optical fiber thereof. The first and second optical waveguide chips are positioned relatively to each other by guide pins intimately placed in the guide grooves, and the inclined end faces extend substantially parallel to each other with an air layer interposed therebetween. An optical component such as an optical transmission/reception module thus produced can easily be reduced in size and cost, and fabricated in an integrated configuration.
摘要翻译：在陶瓷基板中限定V槽和引导槽，并且通过陶瓷基板和盖将光纤固定地设置在V槽中，由此制造第一光波导芯片。在另一个陶瓷基板中也限定V沟槽和引导槽，并且通过陶瓷基板和盖子将光纤固定地设置在V槽中，从而制造第二光波导芯片。第一光波导芯片具有通过光纤的光的传播方向倾斜的端面，第二光波导芯片也具有与通过其光纤的光的传播方向倾斜的端面。第一和第二光波导芯片通过紧密地放置在引导槽中的引导销彼此相对定位，并且倾斜端面彼此间延伸大致平行，空气层插入其间。如此制造的光传输/接收模块等光学部件的尺寸和成本可以容易地降低，并且以一体化的结构制造。
