Optical properties of InxGa1-xN alloy and In0.5Ga0.5N/GaN multi quantum wells have been investigated in the region of far infrared. Far-IR reflectivity spectra of In0.5Ga0.5N/GaN multi quantum wells on GaAs substrate have been obtained by oblique incidence p- and s-polarization light using effective medium approximation. The spectra and the dielectric functions response give a good informa...
static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (qcls) studied theoretically in this paper. the present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. two equations were derived to calculate the noise and modulation response. calcula...
In this paper, a numerical study of barrier characterization effects on the high-temperature internal performance of an InGaAsP multi-quantum well laser is presented. The softwareused for this purpose self-consistently combines the three-dimensional simulation of carrier transports, self-heating, and optical waveguiding. The laser model calculates all relevant physical mechanisms, including the...
The purpose of this study is to investigate the relationship between managers' quantum skills and to improve the decision-making system with an emphasis on the mediating role of policy-making. The research method was descriptive-correlational in terms of practical purpose and in terms of data collection. The statistical population included all members of the faculty of Mazandaran Azad Un...
