    摘要： An optical interconnection arrangement comprises a plurality of substantially parallel optical interconnection channels. In each channel, there are an optical source, an optical receiver, a first lens and a second lens. The first lens conveys light from the source to the second lens, and the second lens refocusses the light at the receiver. Each source and the associated first lens are offset one relative to the other by a predetermined distance in a direction transverse to an optical axis of the first lens. The corresponding receiver and the associated second lens are offset one relative to the other by the same distance but in the opposite direction to the offset between the source and first lens. Each offset is equal and opposite to the corresponding offset in an adjacent channel. With such an arrangement, if a leakage portion of a light beam from a first lens in one channel impinges upon the second lens in an adjacent channel, the leakage portion will be refocussed at a position which is spaced from the receiver of such adjacent channel. In one embodiment, in each channel, the first lens and the second lens share a common optical axis and the source and receiver are offset relative to such common optical axis. In an alternative embodiment, the source and the receiver share a common optical axis and the first lens and the second lens are offset relative to such common optical axis. Such optical interconnection arrangements are tolerant of translational or rotational misalignments between the sources and associated first lenses on the one hand and the receivers and associated second lenses on the other hand, which is of particular advantage for free space optical interconnects or couplers.

    摘要翻译： 光互连装置包括多个基本平行的光互连通道。 在每个通道中，存在光源，光接收器，第一透镜和第二透镜。 第一透镜将来自源的光传送到第二透镜，并且第二透镜在接收器处重新聚焦光。 每个源和相关联的第一透镜在横向于第一透镜的光轴的方向上相对于另一个偏移一个预定距离。 对应的接收器和相关联的第二透镜相对于另一透镜相对偏移一个相同的距离，但是在与源极和第一透镜之间的偏移的相反方向上偏移。 每个偏移与相邻通道中的相应偏移量相等并相反。 通过这样的布置，如果来自一个通道中的来自第一透镜的光束的泄漏部分在相邻通道中撞击第二透镜，则泄漏部分将重新聚焦在与该相邻通道的接收器间隔开的位置处。 在一个实施例中，在每个通道中，第一透镜和第二透镜共享公共光轴，并且源和接收器相对于这样的公共光轴偏移。 在替代实施例中，源和接收器共享公共光轴，并且第一透镜和第二透镜相对于这种公共光轴偏移。 这种光学互连装置在一方面容忍源和相关联的第一透镜之间的平移或旋转不对准，另一方面容纳接收器和相关联的第二透镜，这对于自由空间光学互连或耦合器是特别有利的。
