论文摘要
由于其出色的光子，光声，电声，电声和压电性质，绝缘子（LNOI）晶状体在绝缘子（LNOI）上的商业化引发了显着的片上光子整合应用。近年来，已经实现了各种具有高性能的基于芯片的基于LNOI的光学设备。在这里，我们开发了1个mol \％掺杂的LN晶体及其LNOI晶圆，并制造了具有高质量的Erbium掺杂的LNOI微型风味（$ \ sim $ 1.05 $ \ times 10^{^5} $）。 $ \ sim $ 1530 nm和$ \ sim $ \ sim $ 1560 nm的C波段激光发射显示了974 nm和1460 nm的泵送，并且后者具有更好的热稳定性。该微叠剂将在Niobate锂平台的光子整合电路中发挥重要作用。
The commercialization of lithium niobate on insulator (LNOI) wafer has sparked significant on-chip photonic integration application due to its remarkable photonic, photoacoustic, electro-optic and piezoelectric nature. A variety of on-chip LNOI-based optical devices with high performance has been realized in recent years. Here we developed 1 mol\% erbium-doped LN crystal and its LNOI wafer, and fabricated an erbium-doped LNOI microdisk with high quality ($ \sim $ 1.05$\times 10^{^5}$ ). C-band laser emission with $ \sim $1530 nm and $ \sim $1560 nm from the high-Q erbium-doped LNOI microdisk was demonstrated both with 974 nm and 1460 nm pumping, and the latter has better thermal stability. This microlaser would play an important role in the photonic integrated circuits of lithium niobate platform.
