Abstract
A novel means for interconnecting two optical components is disclosed, in which there are two connecting surfaces with matching surface features, and one optical component is located at a predetermined location on the first surface, and the other optical component is located at a matching location on the second surface. When the two surfaces are mated in a face-to-face fashion, they are locked into a stable position through the matched surface features. The first and the second optical components are aligned properly as they are located at a same spot with respect to the face-locking surface features. The unique surface features and the locations of the optical components may be registered by a lithographic method that has a sub-micron accuracy. Modular approach is feasible in which a combination of face-lock embodiments are stacked together to align a number of optical components. When the surface features has periodic patterns, more than one stable locking positions can be achieved, realizing optical switching capability.
