红外探测器是国防安全、环境监测、医疗诊断、工业检测以及自动驾驶和智能感知等领域的重要基础器件。随着应用场景向高复杂度、低功耗和自主化方向发展,下一代红外系统需要同时具备高探测率、快速响应、多维信息获取、紧凑集成和片上智能处理能力。传统HgCdTe、InSb、InGaAs、量子阱等材料体系仍具有高性能优势,但在制冷需求、暗电流控制、制备成本和功能拓展方面仍面临限制。

近日,复旦大学智慧纳米机器人与纳米系统国际研究院/智能机器人与先进制造创新学院梅永丰教授团队联合中国科学院上海技术物理研究所吴斌民博士、甄红楼研究员等,在材料领域一区Top期刊Advanced Materials发表综述论文《Recent Progress in Infrared Detection From Material Advances to Integrated Intelligent Systems》。该文围绕“材料-器件-系统”三个层级,系统梳理了红外探测从高性能探测单元向集成化、智能化、多功能平台演进的最新进展。

Recent Progress in Infrared Detection From Material Advances to Integrated Intelligent Systems

Growing industrial, environmental, and healthcare needs are accelerating the development of next-generation infrared systems with high detectivity, multifunctional sensing, and on-device intelligence. While traditional devices (e.g., HgCdTe, quantum wells) continue to dominate in terms of performance, they face limitations in cooling requirements, cost, and functionality. Recently, considerable advances have been made in materials, structures, and detection systems. As the foundation of IR systems,  photodetectors based on traditional materials with band alignment engineering and emerging materials (e.g., two-dimensional materials and quantum dots) show high photodetectivity, low dark current, and room-temperature operation. Meanwhile, on-chip microstructures (e.g., plasmons, metasurfaces, and 3D-assembled architectures) integration enables manipulation of coupling and propagation of electromagnetic fields, which enhances polarization and wavelength-dependent light absorption. These developments empower infrared devices with multidimensional photodetection capabilities and tunable spectral response. Furthermore, advanced technologies like in-sensor computing, miniaturized spectrometers, and on-chip digitization merge sensing, storage, and computing into a single chip. The integration enables monolithic infrared systems with more compact architectures while possessing adaptive perception, data compression, and real-time signal processing capabilities. Finally, a comparative analysis containing material engineering, microstructure design, and integrated architecture is presented to outline the challenges and opportunities toward compact, intelligent, multifunctional infrared detection platforms.
