摘要

中红外双梳光谱学是一种强大的快速宽带技术，它涉及到两个梳通过自由空间波束组合而混合并产生热信号。在这里，我们首次展示了通过利用Ge-on-Si平台和3D自对准倒装芯片组装与合成器集成的片上qcl。

Mid-infrared dual-comb QCLs integrated with beam combiner based on Ge-on-Si platform

Mid-infrared dual-comb spectroscopy, a powerful fast and broadband technique involves two combs that are mixed by free-space beam combining and generating beat signal. Here, we demonstrate for the first time on-chip QCLs integrated with combiners by leveraging Ge-on-Si platform and 3D self-alignment flip-chip assembly.
