Phys. Rev. A 69, 013805 (2004) [4 pages]Few-cycle soliton propagationReceived 11 September 2003; published 12 January 2004 Soliton propagation is usually described in the “slowly varying envelope approximation” regime, which is not applicable for ultrashort pulses. We present theoretical results and numerical simulations for both nonlinear Schrödinger and parametric (χ(2)) ultrashort solitons in the “generalized few-cycle envelope approximation” regime, demonstrating their altered propagation. © 2004 The American Physical Society URL:
