In this talk, I will introduce a novel all-optical control scheme based on a double-Λ electromagnetically induced transparency (EIT) system. The property of the double-Λ EIT medium with a closed-loop configuration depends on the relative phase of the applied laser fields. Steady-state analytical solutions for the phase-dependent double-Λ EIT system are obtained by solving the Maxwell-Bloch equations. In addition, all-optical π phase modulation and coherent light amplification at low light levels based on the double-Λ EIT scheme will also be discussed.

Keywords: Double-Λ EIT, All-optical phase modulation, Coherent light amplification
