Abstract :
Size and material type of quantum box are important parameters in an optical waveguide consisting of quantum dot structure. It is shown that the type of quantum box structure directly effects maximum gain of the spectrum. That is down using two different core/shell structures of Al0.24Ga0.76As/GaAs and In0.47Ga0.53As/InP both with the dimensions of 5×5×5nm and 10×10×10nm where it is shown that the gain spectrums differ from each other. Finally we inspect the optical propagation of a quantum box wave guide array and optical energy transfer between adjacent quantum boxes.
