摘要:

从脉泽到激光器,光的相干产生依赖于导致增益的各个发射器的特定结构。在少数发射器限制下作为激光器工作的器件为理解从太赫兹源到量子通信的量子相干现象提供了机会。在这里,我们展示了一个脉泽,是由单电子隧穿事件驱动。半导体双量子点(DQD)作为增益介质,被放置在高品质因数微波谐振腔内。我们通过比较微波激射阈值以上和以下的微波辐射场的统计数据来验证微波激射的作用。

英文摘要:

The coherent generation of light, from masers to lasers, relies upon the specific structure of the individual emitters that lead to gain. Devices operating as lasers in the few-emitter limit provide opportunities for understanding quantum coherent phenomena, from THz sources to quantum communication. Here we demonstrate a maser that is driven by single electron tunneling events. Semiconductor double quantum dots (DQDs) serve as a gain medium and are placed inside of a high quality factor microwave cavity. We verify maser action by comparing the statistics of the emitted microwave field above and below the maser threshold.
