Abstract

Log wavelength optical photons in a quanternary In1−x Gax AsyP1−y alloy are investigated based on the Green's function technique utilizing the concentration-dependent modified rigid ion model (MRIM). In order to obtain four-mode behavior in an A1−xBxCyD1−y quaternary alloy, formation of two cells AB and CD has been considered. In addition to the interactions betwen A, B, C, and D in their concentration ratios with a nonrandom ness parameter, the intercell and the intracell interactions are also taken into account. The results for the In1−xGaxAsyP1−y quaternary alloy are found to be in satisfactory agreement with the available experimental results.
