摘要
A hollow-core fiber with a single layer of robust anti-resonant optical arches is disclosed, which is designed and made of infrared soft glass and allows the transmission of mid- to long-infrared wavelengths (1-15 microns). Each curved arch is solidly attached at two locations on the outer solid region surface and together the arches define the core diameter. The thickness and spacing between the arches are selected to minimize the fiber transmission loss 1 dB/m at wavelengths in the mid- to long-infrared where the infrared soft glass has high absorption 30 dB/m. A hollow-core preform with anti-resonant arches is made by extrusion of infrared soft glasses through a die specifically designed to produce the hollow-core fiber with anti-resonant arches.
