We present an approach of uniformly changing the barrier height of AlGaAs in GaAs/AlGaAs based Terahertz (THz) quantum cascade laser structures for tuning the emission wavelengths. By uniformly changing the aluminum content of all the barriers from 15.5% to 13.5% -in a set of 5 MBE-grown samplesemis
