[ 1 ] - Gain optimization of the optical waveguide based on the quantum box core/shell structure
In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...
[ 2 ] - Effect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...
[ 3 ] - Impressive Reduction of Dark Current in InSb Infrared Photodetector to achieve High Temperature Performance
Infrared photo detectors have vast and promising applications in military,industrial and other fields. In this paper, we present a method for improving theperformance of an infrared photodetector based on an InSb substance. To achieve goodperformance at high temperatures, thermal noise and intrusive currents should bereduced. For this purpose, a five-layer hetero structu...
