Abstract
An optical fiber is interfaced with an optical device formed on a substrate. The substrate includes a groove under and behind an interface between the optical fiber and the optical device. Provision of such a groove allows the substrate to be used for alignment and support of the optical fiber, while reducing fusion loss and improving durability of the interface. Steps for facilitating alignment may be provided in the substrate. Solder may be used to further improve durability of the interfaced structure.
