Abstract
Ferrule assemblies and coupling apparatus as used to form optical interface devices for photonics systems are disclosed. The ferrule assemblies include a ferrule made of a glass substrate and a pair of spaced apart alignment members, which can be made of a glass or a polymer. The ferrule assembly supports an array of optical fibers. The coupling apparatus is incorporated into a photonic integrated circuit assembly that has optical waveguides and that includes spaced apart alignment members, which can also be made of a glass or a polymer. The ferrule assembly and the coupling apparatus have complementary alignment features that align the optical waveguides and the optical fibers when forming the optical interface device. The alignment members have a geometry that allows them to be used to form both the ferrule assemblies and the coupling apparatus.
