Hollow Core NANFs with Five Nested Tubes and Record Low Loss at 850, 1060, 1300 and 1625nm

摘要

Using hollow-core NANFs with 5-nested-tubes, we achieve the lowest loss ever reported in a hollow core fiber at 1300 and 1625nm (0.22dB/km), and in any type of optical fiber at 850nm (0.6dB/km) and 1060nm (0.3dB/km).
