Abstract

We report the experimental observation of bright temporal solitonlike pulses propagating in a material with a negative nonlinearity and positive (normal) dispersion. We believe this to be the first observation of bright solitonic pulses in a material with a negative Kerr nonlinearity. We have observed a gradual narrowing of the output pulse width as a function of increasing input power, and our results agree well with simulations.
