Abstract
The propagation dynamics of a two-mode ultraslow wave in a three level λ system. The probe modes evolved into a two-mode temporally, amplitude and group velocity (TAG) matched pulse pair after a characteristic propagation which travels without distortion and attenuation in a highly dispersive medium with an atomic density as high as 1014 cm-3. Linear and quadratic approximations with numerical calculations were compared for several example using experimental achievable parameters. The results show that four-wave mixing (FWM) process can achieve near unity photon flux conversion efficiency from one mode to the other without the requirement of having maximum atomic coherence.
