A recently granted patent (Publication Number: US11886024B2) discloses a method for creating a monolithic optical waveguide structure. The method involves forming a body with multiple bores extending through it, positioning large diameter optical waveguides in these bores to create separate pathways for independent optical signals, sealing the waveguides within the body, and splicing optical fibers to the free ends of the waveguides. The resulting structure is then placed in a housing and sealed using annular elements. Additional steps include forming orientation features in the body, dicing the structure to create two separate members, polishing the end faces, aligning the waveguides, and using orientation features for alignment.
Furthermore, the patent describes a method for creating a monolithic optical waveguide structure with non-overlapping apertures in the body. Similar to the previous method, this process involves positioning large diameter optical waveguides in the apertures, fusing them to the body, and splicing optical fibers to the free ends. The body can be formed by drawing from a preform or drilling apertures, with the option of including orientation features. Dicing the structure to create two separate members with exposed waveguides is also part of this method, along with ensuring parallel longitudinal axes for the apertures. These innovative methods aim to streamline the production of optical waveguide structures for efficient signal transmission.
