Title: Propagation Dynamics of a Temporally, Amplitude- and Group-Velocity-Matched Two-Mode Ultraslow Wave in a Three-Level Lamda System
Published: December 01, 2004
Abstract: We investigate the propagation dynamics of a two-mode probe field traveling with ultra-slow group velocities. We show that a strong cross-beam coupling occurs between the two modes of the probe wave. In the adiabatic limit and under appropriate conditions, both modes can travel with the same greatly reduced group velocity, and one mode can grow and take on features of the other mode. When only one mode of probe field is injected, the generation and growth of the second mode has four-wave mixing characteristics, resulting in a tunable ultra-slow four-wave mixing field with high flux conversion efficiency.
