Experimental demonstration of spectral sideband splitting in strongly dispersion oscillating fibers.

By using a highly nonlinear, dispersion oscillating optical fiber operating in the telecom C band, we experimentally demonstrate the splitting experienced by quasi-phase matched gain sidebands in the strongly dispersion managed regime of a dispersion oscillating fiber as the power of a continuous-wave pump laser is increased over a certain threshold value. Very good agreement is found between the theoretical predictions and our experimental measurements.
