Phase-controlled gain-assisted slow light propagation in three-coupled quantum wells

The low-intensity light pulse propagation through three-coupled semiconductor quantum wells is studied with the Schrödinger equations. Phase-controlled slow light propagation with little gain is observed in this system. For its flexible design and its wide adjustable parameters, such a semiconductor...

More Information
Summary:The low-intensity light pulse propagation through three-coupled semiconductor quantum wells is studied with the Schrödinger equations. Phase-controlled slow light propagation with little gain is observed in this system. For its flexible design and its wide adjustable parameters, such a semiconductor system is better than its atomic counterpart. Such investigation of properties may provide a new way for realizing slow light and lead to important applications in high-fidelity optical delay lines and optical buffers.
