Claim:
1. An optical assembly having x, y and z axes and comprising: a first substrate having a planar surface, a first wall adjacent and substantially perpendicular to said planar surface, a first register surface adjacent said first wall, at least one foundation to receive an optical element having a first optical axis at least partially along said z axis, wherein said foundation comprises a groove, wherein said first register surface comprises a portion of said groove adjacent said first wall; said optical element having a periphery which contacts said groove to position said optical element in said groove, said periphery having a certain shape; an opto-electrical device (OED) having a top surface, an active area on said top surface having a second optical axis normal to said top surface, and a first alignment element defined on said top surface, said OED abutting said first wall such that said first alignment element extends beyond said first wall and contacts said first register surface to position said OED on said first substrate along at least one of said x or y axes with said second optical axis parallel to said planar surface, wherein said first alignment element has a periphery having said certain shape such that said first alignment element is positioned in said groove along the x and y axes essentially the same as said optical element.
