The recent development of erbium-doped fiber amplifiers has aroused great interest in the observation of coherent pulse propagation in resonant fiber waveguides. The self-induced transparency (SIT) soliton offers a possibility of pulse shaping and standardization that is different from nonlinear Schrodinger (NLS) soliton formation. The guiding of radiation by fiber structure eliminates diffraction effects and makes possible the interaction of the radiation over long distances. To date, however, there has been no report of experiments on SIT solitons and coherent π pulse propagation in a fiber waveguide. In this paper, we describe the observations of self-induced transparency solitons and coherent π pulse propagation in an erbium-doped resonant fiber waveguide. We also describe NLS soliton propagation and the coexistence of NLS and SIT solitons, which contribute to a complete understanding of nonlinear dispersive wave propagation in a resonant medium.
