Abstract
A substrate (10) is formed having first and second opposite flat surfaces. Photolithographic masking and etching is used to form on the first surface of the substrate at least one lens (25) having a central axis. Photolithographic masking and etching is also used to form on the second surface of the substrate an optical fiber guide (23). The fiber guide is then used to mount an optical fiber(27) on the second surface of the substrate such that the central axis of the optical fiber is substantially coincident with the central axis of the lens, thereby giving the desired alignment.
