An optical package includes a sub-mount, an edge-emitting laser mounted on the sub-mount, a collimating ball lens mounted on the sub-mount adjacent to the edge-emitting laser, a mirror mounted on the sub-mount adjacent to the collimating ball lens. The sub-mount is made of a bottom wafer. A lid is bonded to the sub-mount to form the laser package. The lid is made of a middle wafer bonded to a top wafer. The middle wafer defines an opening that accommodates the edge-emitting laser, the collimating ball lens, and the mirror. The opening is defined by vertical sidewalls. The top wafer further includes a lens above the mirror.
