Dissipative Parametric Gain in a GaAs/AlGaAs Superlattice in PHYSICAL REVIEW LETTERS
New study is published in the journal “Physical Review Letters” from American Physical Society in the field of parametric generation of EM oscillations in GHz-THz frequency range. The work reports on the first observation of the dissipative parametric generation in a subcritically doped GaAs/AlGaAs superlattice (SL) subjected to a DC bias and a microwave pump.…
