摘要	Coupling of light from monomode fibres or devices to other fibres or devices is achieved simply and without micromanipulation by the alignment of the outer diameters of optical elements which have common diameters. Lensing is achieved by using a section of multimode fibre (10) to act as a graded index lens. Alignment of devices to the common optical axis can be achieved with no micromanipulation of any of the components. Substrate (42) has a V-groove (44) etched in its upper surface in which is located fibre (6) together with spacer elements (14, 16) and lens fibre section (10). These elements may be secured in V-groove (44) by an adhesive bond or by solder in order to precisely align the elements coaxially with a light transmitting/conducting/receiving device (40) mounted on the side face (46) of optical device (40).
其他摘要	通过对准具有共同直径的光学元件的外径，可以简单地实现从单模光纤或器件到其他光纤或器件的光的耦合，而无需显微操作。通过使用多模光纤（10）的一部分作为渐变折射率透镜来实现感测。可以在不对任何组件进行显微操作的情况下实现器件与公共光轴的对准。衬底（42）具有在其上表面中蚀刻的V形槽（44），其中光纤（6）与间隔元件（14,16）和透镜光纤部分（10）一起定位。这些元件可以通过粘接或焊接固定在V形槽（44）中，以便与安装在光学装置的侧面（46）上的光传输/导电/接收装置（40）同轴地精确对准元件。（40）。
主权项	A light collimating optical system, the system comprising first and second light transmitting/receiving/conducting devices, a section of optical fibre having a refractive index which changes gradually in a radial direction, first and second light conducting means positioned adjacent to the optical fibre section and having a diameter common with that of the optical fibre section and serving to conduct light between the first and second light transmitting/receiving/conducting devices via the optical fibre section, and mounting means serving to hold the optical fibre section and said first and second light conducting means in a common optical axis.
