Abstract

Fiber-based multimode combiners allow for wavelength and power scaling of laser sources while maintaining a common emission aperture and divergence. For applications in the mid-infrared spectral band, chalcogenide glass optical fibers are one of the few alternatives with high-power beam delivery. We demonstrated a 7 × 1 multimode fiber combiner based on a sulfide-based multimode chalcogenide fiber with 76% per-port transmission. Wavelength combining and power scaling in the mid-infrared are demonstrated through the fiber combiner.
