Abstract

Solitons are often proposed for use in communications and optical logic. However, the usual NLS soliton propagation relies on the ``slowly varying'' (SVEA) regime, which fails for ultrashort solitons. Would the extra ``phase twist'' imposed on the propagation of a few-cycle[1] pulse destroy or alter any soliton character? I present theory and simulations demonstrating the altered propagation for both lone solitons and soliton collisions, and discuss the implications. The effect on $\chi^{(2)}$ solitons may also be discussed.
