论文摘要
为了改善微波动力电感探测器(MKIDS)中的光学耦合,我们研究了曲折吸收剂下方的反射板的使用。我们设计,制造和表征了高Q因子基于TIN的MKIDS,在蓝色的光波长下运行,在曲折下方具有AU/NB反射性薄双层。使用透明的Al $ _2 $ o $ _3 $介电层以达到峰值光子吸收,将反射器设置为距蜿蜒的四分之一波距离。我们希望将板通过将其反射回吸收剂来恢复未发现的光子。
To improve the optical coupling in Microwave Kinetic Inductance Detectors (MKIDs), we investigate the use of a reflective plate beneath the meandered absorber. We designed, fabricated and characterized high-Q factors TiN-based MKIDs on sapphire operating at optical wavelengths with a Au/Nb reflective thin bilayer below the meander. The reflector is set at a quarter-wave distance from the meander using a transparent Al$_2$O$_3$ dielectric layer to reach the peak photon absorption. We expect the plate to recover undetected photons by reflecting them back onto the absorber.
