Tunneling-induced ultraslow solitons in triangular quantum dot molecules

Publication date: Available online 25 October 2018Source: Physics Letters AAuthor(s): Dong Sun, Hongjun Zhang, Hui Sun, Xiaowei Li, Gaiying WangAbstractWe theoretically investigate the propagation of a weak probe laser pulse in a triangular quantum dot molecules scheme based on the tunneling induced transparency. We find that the ultraslow optical solitons can be realized due to the destructive quantum interference induced by the interdot tunneling coupling which can be adjusted by the gate voltage appropriately. This work may provide practical applications such as electro-optic modulated devices and other information processes in semiconductor quantum dots structure.
