Bend loss in multimode chalcogenide fiber at infrared wavelengths

Paper Abstract

The bending loss is a critical parameter for packaging, representing a limiting parameter in the minimization of fiber-based devices. For applications in the mid-infrared spectral band, chalcogenide glass optical fibers are one of the few alternatives for high-power beam delivery. We present experimental results for the bending loss of a sulfide-based multimode chalcogenide fiber for a broad range of infrared wavelengths as well demonstrating <5.8  W power handling for a 6.25-mm radius bend.
