Abstract:
1. An optoelectronic assembly comprising: a coupler having first and second coupling surfaces, said first surface having a first beam port and said second surface having a second beam port, said coupler defining a beam path between said first and second beam ports; a substrate having an active optical element, wherein said active optical element is one of a light source and a light detector, said first coupling surface being substantially perpendicular to said second coupling surface; and an elastic averaging alignment arrangement for precisely locating said second beam port of said coupler relative to said active optical element, said elastic averaging alignment arrangement including an array of fixed alignment features on one of said coupler and substrate and including a plurality of flexible alignment features on the other of said coupler and substrate, said fixed alignment features being dedicated to achieving elastic averaging by cooperation with said flexible alignment features.
