Paper Abstract

We report detailed characterization results of Yb-doped Chirally-Coupled-Core (3C) fibers fabricated with Direct Nanoparticle Deposition (DND) technique. Two types of 3C fibers with core/clad geometries of 34/250μm and 55/400μm and another 25/250μm conventional large-mode-area (LMA) fiber are measured and the results are compared in terms of modal content, transmission spectrum, etc. A picosecond fiber amplifier is built based on 55/400μm 3C fiber, showing robust single-mode operation with peak power >1MW with no sign of stimulated Raman scattering (SRS).
