    • A single-mode optical waveguide with a core, surrounded by a cladding consisting of an inner soft layer and an outer harder layer is described. The outer layer has a grating structure on its inner surface, whose spatial frequency is the same as that of the guided mode. The thickness of the inner cladding is sufficient to keep the grating outside the mode field in undeformed regions of the waveguide, so that normally no out-coupling of the light results. Connections are made by crossing two such waveguides at an angle and pressing them together. This results in deformation of the two waveguides such that the gratings are brought into proximity with the cores. Light is coupled out of one waveguide and into the other in the deformed region, resulting in a self-aligning optical connection. The out-coupled light propagates normal to the waveguide axis, so errors in the crossing angle cause little change in efficiency. Because the cladding system is sufficiently resilient to recover after deformation, the connection is remakeable.
    • 描述了具有由包含内软层和外硬层的覆层围绕的芯的单模光波导。 外层在其内表面具有光栅结构,其空间频率与导向模式相同。 内包层的厚度足以将光栅保持在波导的未变形区域中的模场外,使得通常不会导致光的外耦合。 通过将两个这样的波导以一定角度交叉并将它们压在一起而形成连接。 这导致两个波导的变形,使得光栅与芯接近。 光从一个波导耦合到变形区域中的另一个,导致自对准光学连接。 输出耦合光垂直于波导轴传播,因此交叉角的误差几乎不会导致效率的变化。 因为包层系统具有足够的弹性以在变形后恢复,所以连接是可重新制造的。
