Abstract :
In this paper, we report on a novel hollow metallic fiber (HMF) design that offers low transmission loss for mid-infrared (mid-IR) wavelength. The fiber is so designed that it has a dielectric and metamaterial double inner-coating, which can efficiently reflect transverse-magnetic (TM) wave. As compared with a normal HMF structure, the double-cladding reduces the mode guiding loss for TM01 mode and fundamental mode by two orders of magnitude in the mid-IR region.
