The optical constants of GaxIn1- xAsySb1- y MBE epitaxy layers with different compositions were
studied by infrared ellipsometric spectroscopy at room temperature. The refraction indices enhancement
were experimentally observed. The peak values of refractive indices change approximately as a linear
function of composition between x=0.2~ 0.3.
