چکیده انگلیسی
Dynamic propagation and storing-retrieving of a weak infrared (IR)-light pulse in a coupled semiconductor double-quantum-dot (SDQD) structure are studied theoretically with feasible parameters. Two characteristic features are found. First, it is shown that, with a constant control field, the SDQD medium is transparent to the probe pulse which propagates over sufficiently long distances. Furthermore, the pulse shape remains unchanged on propagation. Second, with a time-varying control field, we are able to store and retrieve the probe pulse in this four-subband SDQD medium by adiabatically switching off and on the control field. Such a four-subband SDQD system for storing and retrieving coherent information is much more practical than its atomic counterpart as a result of its flexible design and the controllable (tunable) interference strength and thus provides a new possibility for technological applications in quantum information science in the SDQD solid-state nanostructure.
