Conclusions
  • Phase solitons exist in 4-wave-mixing resonators
  • Bright solitons exist in laser resonators with
    nonlinear absorber
  • (competition in velocity space or coexistence
    of several solitons)
  • Applications possible for optical information
    processing
  • (see paper by Larionova Spatial
    Solitons in Semiconductor Microcavities)
