Abstract
The glass-based ferrules include a glass substrate and two spaced-apart guide tubes, which can also be made of glass. The guide tubes include bores sized to receive guide pins from another ferrule. The ferrule can be used to form an optical interconnection device in the form of a waveguide connector that includes a planar lightwave circuit that supports multiple waveguides. The ferrule can also be used to form an optical interconnection device in the form of a fiber connector that includes a support substrate and an array of optical fibers supported thereby. The waveguide connector and fiber connector when mated form an integrated photonic device. Methods of forming the ferrule components, the ferrules and the optical interconnection devices are also disclosed.
