Controllable generation and spatial phase-modulation of vortex beams in cascade-type atomic ensembles

Yueqian Li, Yan Zhang

We propose a four-level cascade-type atomic system in which two reverse four-wave mixing (FWM) processes can coexist via optical transitions in distinct pathways. This enables the…

Negative refraction with little loss manipulated by the voltage and pulsed laser in double quantum dots

Shun-Cai Zhao, Xiao-fan Qian, Ya-Ping Zhang +1

The paper demonstrates that negative refractive index can be achieved via tuning the tunneling rate between a double quantum dots(QDs) system by applying a bias voltage, and a puls…
