ABSTRACT:
An assembly of fiber optic couplers of substantially identical form in an integrated array comprising two sets of optical fibers arranged side by side across an arcuate surface, epoxied in place, and lapped to develop mating planar surfaces which expose at least partially lapped portions of the respective optical fibers. Preferably, a launch coupler array is provided in which one set of optical fibers is of smaller diameter than those of the other set and is lapped to a depth sufficient to sever the fiber cores. The two lapped faces are then aligned so that one set of severed ends of the smaller fibers is joined with the exposed core portions of the other set of fibers. Selection of fiber size and lapping of the second set of fibers is performed to develop opposed mating portions of individual fibers which are substantially equal in extent and dimensions. After preparation of the two sets of fibers, the mating flat surfaces are joined together and proper alignment is achieved by monitoring light through two couplers at opposite sides of the array until the light transfer is maximized.
