论文摘要
混合超导射光微孔子是实现微波对光转导的有前途的平台。但是，超导体对散射光子的吸收导致意外的微波共振频率变化和线宽宽度。在这里，我们在实验中研究了这种效应的动态及其对微波转换的影响，在综合硝酸锂 - 螺旋杆菌混合谐振器平台中。我们揭示了由薄膜超导谐振器的快速照相子弹引起的腔内微波光子的绝热频率转移。结果，我们的理论模型对电磁转导的时间和光谱响应进行了修改和描述。这项工作提供了有关光引起的转化动力学的重要见解，这些动态必须在混合超导射击系统的未来设计中考虑。
Hybrid superconducting-photonic microresonators are a promising platform for realizing microwave-to-optical transduction. However, the absorption of scattered photons by the superconductors leads to unintended microwave resonance frequency variation and linewidth broadening. Here, we experimentally study the dynamics of this effect and its impact on microwave-to-optics conversion in an integrated lithium niobate-superconductor hybrid resonator platform. We unveiled an adiabatic frequency shifting of the intracavity microwave photons induced by the fast photo-responses of the thin-film superconducting resonator. As a result, the temporal and spectral responses of electro-optics transduction are modified and well described by our theoretical model. This work provides important insights on the light-induced conversion dynamics which must be considered in future designs of hybrid superconducting-photonic system.
