METHOD OF MAKING AN ARTICLE COMPRISING AN OPTO-ELECTRONIC DEVICE AND AN OPTICAL WAVEGUIDE COUPLED THERETO A method for aligning an opto-electronic device such as a semiconductor laser to a waveguide on a substrate is disclosed. The method comprises placing the device onto the substrate such that it is in rough alignment with the waveguide, optically pumping the device such that the device emits electromagnetic radiation, with some of the emitted radiation being coupled into the waveguide and detected by appropriaee means. If indicated by the detector signal, the position of the device is then adjusted until the desired degree of coupling is attained, whereupon the device is mechanically secured to the substrate and appropriate electrical connections made between device and substrate. Devices useful in the practice of the method typically comprise a window in their top metallization layer.
