ABSTRACT:
An optoelectronic apparatus has, a die having a mesa (103) with a surface emitting optical device and a metallized p-type contact (209), a planar pad (201) adjacent the mesa for Z-height registration with an optical bench, a first notch (206) having been provided by a first etch and having thereon a metallized n-type contact (208) that is coplanar with the p-type contact (209), a second notch having a side surface (204) having been provided by a second etch, the second notch to abut the optical bench along an x-axis, the first notch (206) extending to the second notch, and the die having side surfaces (207) to abut the optical bench along a y-axis, and the second notch extending to the side surfaces (207).
