The arrival of the information explosion era is urging the development of large-bandwidth high-data-rate optical interconnection technology. Up to now, the biggest stumbling block in optical interconnections has been the lack of efficient light sources despite significant progress that has been made in germanium-on-silicon (Ge-on-Si) and III-V-on-silicon (III-V-on-Si) lasers. 2D materials and metal halide perovskites have attracted much attention in recent years, and exhibit distinctive advantages in the application of on-chip light emitters. Herein, this Progress Report reviews the recent progress made in light-emitting materials with a focus on new materials, i.e., 2D materials and metal halide perovskites. The report briefly introduces the current status of Ge-on-Si and III-V-on-Si lasers and discusses the advances of 2D and perovskite light-emitting materials for photonic integration, including their optical properties, preparation methods, as well as the light sources based on these materials. Finally, challenges and perspectives of these emerging materials on the way to the efficient light sources are discussed.
信息爆炸时代的到来推动着大带宽、高数据速率光互连技术的发展。到目前为止，尽管硅基锗（Ge-on-Si）和硅基III-V族（III-V-on-Si）激光器已取得显著进展，但光互连中最大的绊脚石一直是缺乏高效光源。二维材料和金属卤化物钙钛矿近年来备受关注，并且在片上发光体应用中展现出独特优势。在此，本进展报告回顾了发光材料的最新进展，重点关注新材料，即二维材料和金属卤化物钙钛矿。报告简要介绍了硅基锗和硅基III-V族激光器的现状，并讨论了用于光子集成的二维和钙钛矿发光材料的进展，包括它们的光学性质、制备方法以及基于这些材料的光源。最后，讨论了这些新兴材料在通往高效光源道路上的挑战和前景。
