Probability and loss ratios in semiconductor single step index lasers

Abstract

In this work, probability and loss ratios for least mode even and odd fields in the semiconductor single step-index lasers with alpha method are theoretically have been studied and validities of novel found formulas are confirmed and compared with each other numerically: That the results for the least mode even and odd fields are also marginally different has been seen. These accurate differences on the asymmetric and symmetric cases have reflected to the quantities, such as normalized propagation constants, confinement factors depend on them, propagation constants of the regions, wave numbers are the same accuracy, has been understood in the numerical samples clearly. But, unless the refractive indices are changed, that phase constants, phase velocities, effective indices and energy levels of active region are the same has been evaluated.
