Back-seeding of higher order gain processes in picosecond supercontinuum generation
Peter M. Moselund, Michael H. Frosz, Carsten L. Thomsen, Ole BangIn photonic crystal fibers with closely spaced zero dispersion wavelengths it is possible to have two pairs of four-wave mixing (FWM) gain peaks. Here, we demonstrate both numerically and experimentally how the outer four-wave mixing gain peaks can be used to produce a strong amplification peak in ... [Opt. Express 16, 11954-11968 (2008)]
