Abstract
An optical package is provided having a diode mounted to a substrate enclosed by a housing which includes a bore for receiving an optical waveguide and a focusing element adjacent the bore. The bore and focusing element are aligned along a common optical axis. An alignment means is associated with the housing for aligning the substrate along the optical axis.
