N2 - The authors report on midinfrared photoreflectance measurements of the band gap (E0) and spin-orbit splitting energies (0) in InAs-rich InAsSb and GaInAsPSb samples for varying antimony contents 22.5%. The E0 behavior as a function of Sb content is consistent with the literature value bowing parameter of ~670 meV. However, 0 does not exhibit the positive bowing of +1170 meV quoted in the literature: rather, a best fit to their data tentatively suggests a negative bowing of −225 meV. This result is likely to have strong impact due to the importance of the 0 parameter in governing InAsSb-based device performance.
