Parabolic pulse generation with active or passive dispersion decreasing optical fibers
TLDR
It is shown that a hybrid configuration combining dispersion decrease and gain has several benefits on the parabolic generated pulses.Abstract:
We experimentally demonstrate the possibility to generate parabolic pulses via a single dispersion decreasing optical fiber with normal dispersion. We numerically and experimentally investigate the influence of the dispersion profile, and we show that a hybrid configuration combining dispersion decrease and gain has several benefits on the parabolic generated pulses.read more
