论文摘要
尼贝特薄膜锂已经显示出对从单光源到高带宽数据通信系统的可扩展应用的希望。但是，实现下一代高性能古典和量子设备的光损失比目前的现状要低得多（$ \ sim 1000万美元）。不幸的是，尚未探索离子切片的薄膜锂的物质局限性，因此目前尚不清楚该平台如何实现高质量的因子。在这里，我们评估了薄膜锂液化光子平台的材料有限因子，可以高达$ q \ $ q \ times10^{8} $在电信波长时，对应于0.2 db/m的传播损失。
Thin-film lithium niobate has shown promise for scalable applications ranging from single-photon sources to high-bandwidth data communication systems. Realization of the next generation high-performance classical and quantum devices, however, requires much lower optical losses than the current state of the art ($\sim$10 million). Unfortunately, material limitations of ion-sliced thin-film lithium niobate have not been explored, and therefore it is unclear how high-quality factor can be achieved in this platform. Here we evaluate the material limited quality factor of thin-film lithium niobate photonic platform can be as high as $Q\approx 1.8\times10^{8}$ at telecommunication wavelengths, corresponding to a propagation loss of 0.2 dB/m.
