Fabrication of multiple parallel suspended-core optical fibers by sheet-stacking
We demonstrate a novel optical fiber with multiple parallel air-suspended cores fabricated by the sheet-stacking method. No extra scattering loss from the fabrication process was observed in a fabricated dual air-suspended core fiber. We propose to use the multiple parallel suspended-core fibers as an optical fiber device for tuning dispersion. Fusion splicing has been successfully used to connect such a multiple suspended core fiber with a conventional silica fiber.
