摘要

对超高容量数据传输日益增长的需求要求采用先进的多路复用技术和高速调制。密集波分复用（DWDM）技术在过去几十年中得到了广泛的应用，而绝缘体上铌酸锂（LNOI）最近在高速电光调制中显示出显著的优势。然而，由于材料的各向异性和结构的不对称性，在x切割LNOI上实现DWDM组件面临着挑战。本文重点介绍了用于DWDM系统的x切割LNOI光子发射器和滤波器的最新突破，重点是级联多模法布里-珀罗腔和无各向异性阵列波导光栅。这些创新的光子器件，以及它们卓越的性能，增强了LNOI光子学在开发高容量光数据传输和光信号处理的多功能光子集成方面的吸引力。

Photonics Breakthroughs 2024: Lithium-Niobate Photonics for Dense Wavelength-Division Multiplexing

The growing demands for ultrahigh-capacity data transmission require advanced multiplexing for multiple channels together with high-speed modulation. The dense wavelength-division multiplexing (DWDM) technology has been widely utilized over the past few decades, while lithium-niobate-on-insulator (LNOI) has recently shown significant benefits for high-speed electro-optic modulation. However, the implementation of DWDM components on x-cut LNOI faces challenges due to material anisotropy and structural asymmetry. This paper highlights recent breakthroughs in x-cut LNOI photonic transmitters and filters for DWDM systems, focusing on cascaded multimode Fabry-Perot cavities and anisotropy-free arrayed waveguide gratings. These innovative photonic devices, along with their excellent performance, strengthen LNOI photonics to be compelling for the development of multifunctional photonic integration available for high-capacity optical data transmission and optical signal processing.
