Paper Abstract

Yb-doped hybrid fiber with anomalous dispersion of 100-380 ps/(nm⋅km) near 1 μm was demonstrated. Single-mode propagation was achieved by selective mode amplification of the hybrid mode: only central part of the core was doped with Yb-ions, which allowed preferences for hybrid mode amplification (suppression of undesirable modes can exceed 20-30 dB, when splice conditions are optimized). Usage of the developed fiber as non-linear pulse compressor allowed us to demonstrate pulses with duration of 250 fs and peak power in excess of 3 kW.
