摘要

我们报告了对基于氮化钛(TiN)的动力学电感探测器(KID)的新颖光学设计的模拟,以改善其对光学光子的响应。我们建议将蜿蜒线与基底分离,以捕获由光学光子产生的热声子,阻止它们在基底中快速传播。这些声子反过来又会促进更多库珀对的断裂,从而提高探测器的响应速度。在我们的设计中,蜿蜒器悬浮在基底上方几百纳米处。此外,还可以在蜿蜒器下方放置反射金(Au)或铝(Al)层,以改善光波长中的光子耦合。

Design and Simulation of TiN-Based Suspended Meander Kinetic Inductance Detectors (KIDs) for Visible and Near-Infrared Astronomy Applications

We report on simulations of a novel design of optical design of optical titanium nitride (TiN)-based Kinetic Inductance Detectors (KIDs) in order to improve in order to improve their response to optical photons. We propose to separate the meander from the substrate to trap hot phonons generated by optical photons, preventing their rapid propagation through the substrate. These phonons would in turn contribute to the breaking of more Cooper pairs, thereby increasing the response of the detector. In our design, the meander is suspended a few hundred nanometers above the substrate. Furthermore, reflective gold (Au) or aluminum (Al)-based layers can be placed under the meander to improve photon coupling in the optical wavelengths.
