Multiple-quantum-well diodes (MQW diodes) naturally have key functionalities of light emission, transmission, modulation and detection all at the same time, enabling new forms of information and energy conversion between photons and electrons. When approximately biased and illuminated at the same time, a multifunctional MQW diode allows simultaneous light emission and detection within a single diode. A single-chip imaging system that uses a 4 × 4 MQW diode array is experimentally demonstrated here that can simultaneously transmit light and capture an image, showing the great development potential of advanced monolithic III-nitride information systems.

同时传输光的单芯片成像系统

多量子阱二极管（MQW 二极管）自然同时具有光发射、传输、调制和检测的关键功能，实现了光子和电子之间的新形式的信息和能量转换。当大约同时偏置和照明时，多功能 MQW 二极管允许在单个二极管内同时进行光发射和检测。这里通过实验证明了使用 4 × 4 MQW 二极管阵列的单芯片成像系统可以同时传输光和捕获图像，显示了先进的单片 III 族氮化物信息系统的巨大发展潜力。
