Abstract: Technologies for beam expansion in monolithic glass substrates are disclosed. In an illustrative embodiment, lenses in a glass substrate may be formed using a laser, either by changing the index of refraction or as part of a two-step etching process. A seam may be prepared and etched, separating the glass substrate into two components, one of which will be part of an optical plug and one of which will be part of an optical receptacle. The optical plug has a cavity into which an optical fiber can be placed. In use, the lens in the glass substrate of the optical plug collimates light from the optical fiber into a beam. When the optical plug is mated with the optical receptacle, the beam is aligned to the lens and a waveguide in the optical receptacle. The large size of the beam relaxes the alignment tolerance for the optical plug and receptacle.
