Research output: Contribution to journalArticlepeer-review


We report the experimental manifestation in optical physics of wave propagation involving self-steepening without concomitant self-phase-modulation. The conditions are realized through the interplay of quadratic and cubic nonlinearities in a frequency-doubling crystal. The experiment constitutes the physical realization of the Chen-Lee-Liu equation, a derivative nonlinear Schrödinger equation that governs pulse propagation.
