Abstract

Specific features of mechanical-stress relaxation in InGaAsP/InP heterostructures for 1064 nm laser radiation converters have been studied. It is established that stress relaxation via the formation of an ordered relief on the surface of solid-solution layers in InGaAsP/InP heterostructures with indium content up to 80% can decrease the probability of spinodal decomposition of the solid solution, enhance its photoluminescence intensity, and increase the efficiency of laser-radiation conversion.
