Abstract

We propose two alternative scheme for highly efficient nonlinear interaction between weak optical fields. The first scheme is based on the attainment of electromagnetically induced transparency simultaneously for two fields via transitions between magnetically split F = 1 atomic sublevels, in the presence of two driving fields. The second scheme relies on simultaneous electromagnetically‐ and self‐induced transparencies of the two fields. Thereby, equal slow group velocities and giant cross‐phase modulation of the weak fields over long distances are achieved.
