## 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.
