摘要
A passive alignment system is provided that comprises one or more first meltable elements disposed on a surface, one or more second meltable elements disposed on a surface and one or more first standoff devices. The first and second meltable elements transition from first and second pre-molten states, respectively, to first and second molten states, respectively, when subjected to first and second temperatures, respectively. In the first molten state, the first meltable elements control relative alignment between the surfaces in first and second dimensions. In the second molten state, the second meltable elements and the first standoff devices control relative alignment between the surfaces in a third dimension. The passive alignment system is suitable for use in a parallel optical communications module to precisely passively align ends of a plurality of optical fibers or waveguides with respective light sources or light detectors of the module.
