  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.
