We conducted experimental studies based on the hypothesis that combining a metamorphic InGaAs buffer with a Type-II material could overcome the limitation on the number of wells caused by lattice strain, which is a problem on GaAs substrates. We confirmed an increase in photoluminescence (PL) intensity from the quantum wells around 1.3 µm following the introduction of the InGaAs buffer.
