摘要翻译：
我们考虑了单微带超晶格中电子在直流和交流电场作用下的高频响应。交流电场的作用使电子的有效质量在微带内发生振荡，产生参量共振。我们建立了在谐振状态下相敏参量放大的理论可行性。参量放大不需要在负微分电导条件下操作。因此，可以防止在超晶格内部形成破坏性的高电场畴。在这里，我们集中讨论电磁辐射从可用频率到理想的太赫兹频率范围的参数上转换和下转换。

英文摘要：
We consider a high-frequency response of electrons in a single miniband of superlattice subject to dc and ac electric fields. Action of ac electric field causes oscillations of electron's effective mass in miniband, which result in a parametric resonance. We have established a theoretical feasibility of phase-sensitive parametric amplification at the resonance. The parametric amplification does not require operation in conditions of negative differential conductance. Therefore a formation of destructive domains of high electric field inside the superlattice can be prevented. Here we concentrate on the parametric up- and down-conversion of electromagnetic radiation from available frequencies to desirable THz frequency range.
