论文摘要
具有高性能的超宽带成像设备对各种技术应用，包括成像，遥感和通信。基于P-GAAS同型界面工作函数内部光发射（HIWIP）检测器 - 光线发射二极管（LED）设备，实现了超宽带上连接器。该设备展示了从可见到Terahertz（THZ）的超大响应，具有良好的可重复性。中红外（miR）区域的峰值响应性为10.5微米为140 mA/w。 Hiwip-LED显示出涵盖所有红外大气窗口以及THZ区域的超宽带上转换的巨大潜力，并进一步证明了MiR斑点的无像素无像素成像。此外，提出的上连接器还通过使用双官能LED在零偏置下作为近红外且可见的检测器执行。由于其超宽的响应，HIWIP领导的上连接器对稳定的高性能超宽带像素无效成像和多功能分析系统具有巨大的希望。
Ultra-broadband imaging devices with high performance are in great demand for a variety of technological applications, including imaging, remote sensing, and communications. An ultra-broadband up-converter is realized based on a p-GaAs homojunction interfacial workfunction internal photoemission (HIWIP) detector-light emitting diode (LED) device. The device demonstrates an ultra-broad response ranging from visible to terahertz (THz) with good reproducibility. The peak responsivity in the mid-infrared (MIR) region is 140 mA/W at 10.5 microns. The HIWIP-LED shows enormous potential for ultra-broadband up-conversion covering all infrared atmospheric windows, as well as the THz region, and the pixel-less imaging of the MIR spot from the CO2 laser is further demonstrated. In addition, the proposed up-converter also performs as a near-infrared and visible detector under zero bias by using a bi-functional LED. Thanks to its ultra-wide response, the HIWIP-LED up-converter has great promise for stable, high-performance ultra-broadband pixel-less imaging and multi-functional analysis systems.
