The four-level inverted-Y configuration realizable in an asymmetric quantum well system interacting with four fields is studied to demonstrate the phenomenon of phase-dependent electromagnetically induced transparency (EIT) in this system. The system is studied under various parametric conditions to demonstrate the controllability of EIT, dispersion properties, and group velocity.

We analyze backward four-wave mixing in a four-level system exhibiting electromagnetically induced transparency (EIT). We show that EIT suppression of the linear absorption leads to the resonantly enhanced four-wave mixing process and the conversion efficiency near 100% may be achieved in a dense four-level medium with negligible decoherence decay.
