Study of methods for lowering the lasing frequency of a terahertz quantum-cascade laser based on two quantum wells

Two mechanisms for achieving lower terahertz-range frequencies in quantum-cascade structures with two quantum wells based on GaAs/AlGaAs compounds are proposed. The first mechanism is based on the introduction of composite quantum wells consisting of a narrow (∼2 nm) quantum well with a low potentia...
