Abstract

A method of arranging a network of optical fiber ends opposite a corresponding network of waveguide ends of a semiconductor wafer displaceable with respect to each other in orthogonal directions X and Y, the method including: arranging the fibers so that the network ends have the same orientation and that the projection of the axis of each fiber on the wafer is parallel to direction Y; injecting, into one of the fibers, a light beam having a wavelength such that light is scattered from the fiber walls, locating the fiber axis, and displacing the fibers or the wafer in direction X to align a characteristic point in line with the projection of the fiber axis on the wafer.
