To achieve precise, hermetic, and reliable optoelectronic packaging, we studied a novel technology for bonding fibers to v-grooved chips by metallic soldering. Multilayered metallization of Ti/Au, Ti/Cu/Au, or Ti/Ni/Au has been prepared to improve the poor bonding nature of solder on oxide surface. The eutectic 43Sn57Bi (wt.%) alloy, having a melting point of 139°C, was selected to bond the fibers to v-grooved chips. The alignment and adhesion tests result show that the precision packaging by soldering has a satisfied reliability in the range of working temperature from -40°C to 85°C. The metallic solder bonding is hermetic, and hence, it can isolate the optical device from ambient environment.
