Patent ID: 7750356

Claim:
A package, comprising: a sub-mount defining a cavity, the sub-mount comprising a bottom wafer and a middle wafer atop the bottom wafer, the middle wafer having crystal planes oriented at oblique angles from a surface of the middle wafer, the middle wafer having a first sidewall and a second sidewall formed therein, the first sidewall comprising a turning mirror, the bottom wafer defining a bottom cavity surface, the cavity extending between the first sidewall and the second sidewall, the second sidewall oriented along a first crystal plane, the first sidewall comprising a wedge-shape with a top angled portion and a bottom angled portion meeting at a wedge point above the bottom cavity surface, the top angled portion comprising the mirror and oriented along a second crystal plane, the bottom angled portion oriented along the first crystal plane parallel to the second sidewall; an edge-emitting laser mounted on the bottom cavity surface adjacent to the first sidewall so the edge-emitting laser is opposite the minor; and a lid comprising a top wafer, the lid mounted atop the sub-mount, wherein the turning mirror directs a light from the edge-emitting laser through the lid.
