摘要

0.661In0.339N0.0554As0.9446/GaAs quantum dot for the potential applications of desired wavelength in fibreoptical communication networks. The band alignment is found using band anticrossing model and the model solid theory. The electric and magnetic fields related electron-heavy hole transition energies as a function of dot radius in a GaInNAs/GaAs quantum dot are studied. The resonant peak valuesof optical absorption coefficients dot are obtained in the presence of electric and magnetic fields. The simultaneous effects of electric and magnetic fields on the threshold current density and the maximum optical gain are obtained in a GaInNAs/GaAs quantum dot. The optical gain variationsas a function of wavelength are found in the presence of magnetic and electric fields. 25% of increase in optical gain is observed with the application of one tesla of magnetic field strength whereas 15% of decrease in optical gain is obtained with the application of one kV/cm of electricfield for a 40 ? quantum dot. The results show that the optimum wavelength for fibre optical communication networks can be obtained with the variation of applied magnetic field strength and the electric field. The outcomes may be useful for the design of efficient lasers based diodesin dilute nitride quaternary semiconductors.]]>
