ABSTRACT:
The present invention involves a combination of active and passive optical or opto-electronic device alignment techniques. Passive alignment is used for two axial lateral directions and all three axial rotational directions (yaw, pitch and roll). In such passive alignment, only the substrate is micromachined with passive alignment structures. One-dimensional active alignment is then used for the remaining axial lateral direction.
