Replacing small amounts of As with Bi in InGaBiAs/InP induces large decreases and increases in the bandgap, Eg, and spin-orbit splitting, ?SO, respectively. The possibility of achieving ?SO?>?Eg and a reduced temperature (T) dependence for Eg are significant for suppressing recombination losses a...
