Low cost materials and processes for OE packaging

This paper describes the adhesive selection process for a 10 Gbps optical transmitter package assembly. In this package, adhesives are used in a fiber and lens bonding application. The behavior of adhesives under selected reliability testing conditions is described. Five UV/visible curable adhesives for the fiber to silicon optical bench bonding were identified, based on their properties, and studied to arrive at a selection methodology. In summary, this study shows that the adhesive characteristics have a major impact in the ability of adhesives to retain the coupling during cure and service life. OE packaging with low cost materials and process has been suggested using UV/curable adhesives. The results of the study are presented in this paper.
